I've been seeing this girl, Jane, about once per week or once every two weeks for about 7 months now. It started out very casual, but we began talking more and more as we realized we actually had things in common and liked each other alright, and we've gone on casual dates together here and there also. I've introduced her to people from work on two occasions (different group of people each time), and I helped her move. She is the only girl I've done these sorts of things with, though I have not been monogamous at all as I have a variety of other girls in town and in other towns I visit sometimes who I occasionally hook up with as well as random flings once in awhile. Jane and I talked early on about keeping things light and how neither of us were looking for a relationship, and both of us are very independent and don't like feeling tied down to anything or anyone, so I didn't see this as a problem...
However, we recently had a really good day together and were more emotionally intimate, and I this got both of us thinking. Jane finally spoke up and we talked about us, the whole "what are we" talk, and though she said she's okay with continuing as things are, keeping things light as FWB, it's pretty clear she would like to be more, be exclusive with each other and go on real dates like weekend trips and stuff like that. This would all be fine for most people, but I have a very strong aversion to relationships and "letting people in." Part of this is a result of my childhood and relationship with my parents, and part of it is from two different relationships I've had where the girl went psycho and literally tried to ruin my life (pretty sure one girl had BPD; she spread horrible rumors about me to a lot of people and it ended up with me having to find another job and losing half of my friends). I have a very good life as is, and I don't really want to change it at all, and risking going through what I've gone through in the past is kind of too much to even wrap my head around. I like Jane, but I don't see us getting married or anything. At the same time I don't really want to lose her...
Any thoughts? Not sure if it matters, but I'm 29 and she's 22.
