I recently went to another city for a week (the city I am considering moving to in future) and met up with a person I've talked to on some dating site. When we were talking online, it was clear that there was chemistry but it was also clear that we are very different people. However, I liked her confidence, persistence and attention so we continued talking.

When we finally met in person, we spent more than 12 hours together, had couple drinks and almost had sex. Next time we met I ended up going to her place (this time fully sober) and staying over.Then we were seeing each other every day (she had to travel for about an hour each time to see me) and I ended up moving my stuff to her place in the end of my vacation.
At some point she asked me to try long-distance and I agreed. I was completely infatuated and now that I got back home.. I do not think it was a right thing to do.

Here is why: This person is a bag of red flags (from my perspective) :\ She drinks more than three times a week, does not have a regular job, many people in her family are recovering alcoholics (her family is quite broken and she grew up in a crazy environment...), she lives off welfare and does not seem to care about finding actual job.. Her room is Extremely messy and she did not graduate high school. I am piling up a bunch of facts, thank you for bearing with me and reading this, if you got this far

I am just feeling frustrated, because I feel huge sympathy for this person, it seems like people were not treating her well at all and I want to help, just as a human being. Another issue is that she is almost 10 years older than me (i am 23) and her health is a messed up because she used to do drugs (hasn't been doing any for the last 8 yrs - except for alcohol and cigarettes...).
I really don't want to be with someone like that and at the same time I feel for her, she is so adorable, attentive and caring. But it feels like we are coming from very different worlds. She is pretty much a ghetto child but a part of me just wants to show her a 'better world' and is hoping she can change. She did say that I make her 'a better version of herself', she drinks and smokes less (but it still feels like A Lot for me....) and feels differently.

I never had such a chemistry with someone before and I feel comfortable with her - although I am afraid to bring up all these things that worry me.. I do bring them up but very gently.

She seems to be very much in love with me currently but I am almost hoping the feelings will fade away while we are apart. She does want to come visit me (she'll have to spend a while saving $ for it, though...) and I can go visit her. I really miss her and have feelings for her but from a rational perspective, this is a person I'd like to be with. I also feel like it sucks to break up with someone on a distance.

*writing this out really helps.. but I do need someone's advice, please..
