So I've been dating this girl that I met about a year ago for the last 4 months or so. We started hanging out after seeing each other at some random party (one of those, hey I remember meeting you deals). Since we started hanging out there hasn't been a day where we haven't talked to each other in some way, shape or form. She is really easy to talk to and we both seem to get along very well.
Here is the thing, she has only had one serious boyfriend in her life (4 years) and he was in the military. She ended up cheating on him and it created a viscous cycle where they would just cheat on each other but remain together (dysfunctional I know..). He was her first (when she was 15) and now she is 20. She has been straight forward about the whole thing when I bring it up. They broke up for good in January of this year.
I'm the only other guy she has introduced to her parents (who seem to like me) other than her ex. I went to Santa Monica yesterday with her and her family, they will sort of joke about me because people think we are boyfriend/girlfriend but she always introduces me as her "friend". I have told her that our relationship (whatever it is) has gotten to the point for me where I want it to be exclusive and if it isn't then I can't keep dating her (I'm doing this to protect myself in a way). When I bring this up (I have a couple of times over the last month or so) she tells me that she can't have a boyfriend but she understands that if she were to date other guys I wouldn't be there anymore.
Is this her subtly telling me that I'm about to get used or is this because of some insecurities she may have because of her past relationship? I'm not sure and its tough for me to think clearly here because I do like her (sort of puts the blinders on).
Now I also know that she did the whole party girl thing for a while after the breakup with her ex. When we started hanging out this was obvious because her phone would be going off during booty call hours. She would tell me when other guys (that she had hooked up with before) wanted to hang out with her somewhat indirectly when we would be texting but ultimately not end up hanging out with them. Or at least I don't think she was (If she was then why would she be telling me that they are texting her right?). She also is the kind of girl who is very dependent on her phone and rarely leaves it unattended.
I really hope that someone here can help me figure out what is going on here and give me another perspective on this whole situation. I really do like this girl enough to make her my gf but not if I'm going to be the guy who gets cheated on and lied to throughout the whole relationship. If she were to cheat on me that would be the end of it for sure, no matter what I feel for her (just my view on relationships). My question to you guys is should I be pursuing this relationship further or does this only spell bad news in my future? I am 22, have a lot going for me and I'm very loyal when it comes to girls that I like (never have cheated and never plan to).
