a guy friend who jumped to "stalker level

I am guy and I have this friend and we used to hang out from time to time and now all of a sudden he always has to be near me and talking to me. I was hanging out with some of my other friends on Saturday making a movie like we always do and me and my friend were taxting and I said "we can maybe hang out today, it depends when I get done here, im guessing 1-2 o'clock" and once 12:30 hit my phone rang none stop from this kid. I would answer and tell him I will call him when I am done. come to find out he was sitting on a dirt road by my other friends house for hours waiting for me. today I went fishing with the friend I make movies and my "stalker" followed us to a gas station and we thought we lost him and when we were done fishing I found one of my hats on my fishing buddies hood, a hat I forgot in my "stalker" friends truck the other day. it was just sitting their. im starting to get freaked out. my brothers getting angry. im getting pushed to my breaking point and im gonna lose it. I hate fighting, I don't unless I have to. but im actually scared that this kid will get into my house while im sleeping or not home. I have no clue how to handle this

can you just ask him? he sounds very lonely. sorry it's freaky for you

He seems clingy , reply with "sorry I am busy" about a couple days later. "I will" would make him think about it the whole day.

I would feel bad because he might just want to socialize, but he's doing it inapproprirately, doesn't he have your other friends to chill with?

he pushed everyone away.

he is on the mentally unstable side. that's why I don't know how to handle it. I care about the kid, he is a good friend but he has reached stalker level in my book. if it was someone else I would tell them off

What is this persons age? Sounds like he may really need a friend/help. maybe?

he is 18 a year younger then me. none of my other friends like him because the way he acts and he lies about everything. we were driving and he pulled out in front of someone and they honked their horn at him and he started freaking out like its their fault. he is making it hard to be his friend. he is not only gonna get himself in trouble he is gonna get me in trouble as well. I cant have that.

I'm thinking....
Are you guys still living with family or at college...are there older people who know him that you can ask for help?
You don't have to be responsible for him, but it is nice that you are concerned.
It doesn't sound promising for a friendship right now. To me.

I'm think a restraining order. This does not sound like a normal person's action.

we still llive aat home. I just don't know

This friend of yours need a therapist. He is insecure and that is why he is acting this way. It is true he is pushing others away by his behavior but has anybody really thought about the reason behind such a behavior?
