Issues with someone I know

While this isn't a romantic relationship I'm talking about, this looked like the only place that could perhaps provide some insight into what is going on in my situation.

There is this acquittance of mine throughout my very recent years of high school who appears to lie on a constant and causal basis. First off in high school he claimed to hangout with the "popular" and "cool" crowd and went to their parties beach week etc., however when I asked one these clique members about him they really had no idea who he was. I also never really observed him associating with these school social groups ether. For example, also back in high school he claimed his family own a Porsche, a hummer, and other extravagant automobiles-they do not. Also he claims his parents are doctors, cologne salesman, work in prominent sales/management positions-they do not.

Additionally, he claimed his father had memberships to at least two prominent country clubs in the area-they most likely do not. When college admissions time came around, he claimed he applied to schools like George Washington, Georgetown, Penn State, Columbia, NYU, Stanford, William & Mary and list goes on. He also claimed he got grants and scholarships from schools like Columbia and William & Mary, furthermore at the time he claimed he a candidate for Harvard Dental School and that he had an interview with them. When I hung out with him throughout the year after he graduated he claimed at first that he was going to a local community college but the first semester he would be going to Georgetown University in Washington DC, so whenever I hang out with him he claims to go to Georgetown in which he was making all A's at academically.

Furthermore recently he claimed he was admitted to the University of Toronto and UNC-Chapel Hill's pre- med/pre-dental program. He also has a linkedin profile(which vary few people at this age have despite the immediate time after high school being the beginning of one's academic and professional career) in which he was seeking contacts and in which he most likely truthfully(one of the small handful of times) claimed to go to the local community college.

On Facebook he always posts about how great things are going for him and his great wins in life and so, as well as trying to project a very good image of himself that stands out from your typical person on the site. Now he is at the university I'm at throughout this year(which is still very strong academically and prestigious from Georgetown University because his brother goes there" and his parents want him to graduate along with his brother".

Along with these pile of lies both small and big, he continues to reinforce periodically that he is getting all these great and prestigious internship oppertunites and part time jobs so on and so forth.

To add more,

I thought maybe he was only lying to me about all these things, however talking to people at school and at my part-time job who knew him from school, he told them the same or varied lies about his life and everything else. He also appears to show no hesitation or difference in acting when telling a lie, so he is therefore very good at lying and can be convincing many times.

In addition, overall for attempting to appear smooth he doesn't he appear to be that adept socially as he often comes off as shallow, arrogant and ignorant, self-centered, and condescending(at times). For example, he frequently liters, referred to someone I knew who had ADD "as by the book retarded", and wears $200-500 dollar clothing(which I know he most likely can't afford). He also comes across as materialistic as he orders the latest Ipod, Iphone, etc as soon as it comes out, and listens to stereotypical music.

He claims to hold a job(which I truthfully don't know if he does), however in the age-range I'm discussing the jobs available usually wouldn't be able to support this type of lifestyle. He has claimed jobs such as intern at a major news corporation and law firm, job where he makes $30 an hour etc.

While I was in high school with him he appeared to do well in school(for example he made National Honor's Society for the last two years of school), however again he often ignorant(for example he didn't know what communism and other concepts where), and in one class I was in he often cheated and plagiarized the work of others.

Of course I know little of his life other then what I see and hear from him.

Also in high school, he at times pressured me for money. As well as around Christmas time as an exchange of gifts in which he didn't follow through with his. And even tried to extort me one time(long story)

Recently, though in the past year or so he has begun to act differently in the sense that he has been acting more like me. I.e. he all of a sudden shows the same interests as me, takes the same positions as me, etc. Some which I find very suspicious and odd. Needless to say he doesn't come across as himself with this.

Also btw one last thing, he is always trying to get me to hang out with him and wonder why he is doing this? And he has gotten extremely angry with me at times when I consistently refuse time with him. ex. one time he facebooked me calling me a real pos, then defriended me, followed by a slew of text messages calling me a number of words. He came crawling back of course.

So I'm wondering what am I dealing with here, and how should I best distance myself from this guy. I'm also a male fyi, and this is non-romantic in nature. He seems pretty mallow recently

Welcome! Glad you could vent this out. It sounds like this has been troubling you for awhile!

I started to gloss over on the examples of how he may not have been truthful. I think you are dealing with a guy who wants to be important and popular...

How to deal with...based on your last comments about how he got angry...probably blocking text, email, facebook, etc. may be the best thing. If you think there is any value to the relationship (which I really didn't get the sense), then you can sit down with him and discuss his tall tales and that you would really like to be a friend but this behavior plus his anger makes it difficult.

Any other opinions out there?

Yes it has been,

So I was wondering what am I dealing with here?
