Okay for all of those that have replied so far, there is more to this story than meets the eye. Basically my girlfriend is outgoing, bubbly, and has an overly friendly nature (which I'm not particularly used too), she has a past, in which she's slept with a lot guys and a few girls. A couple of which are on my course.
Secondly, me and her have different views on behaviour whilst out, she finds it acceptable to dirty dance with friends (whilst drunk), whereas I'm very conservative and class this as wrong. We're exclusive so this sort of stuff is off limits-- as a given!
We've only been going out for a few months and were long distance due to circumstances with her summer arrangement. This inevitably makes it harder for me, with all the things I know to trust, and all of the other issues in my original OP get on top of me.
Particularly more the said friend that she's known a mere few weeks, and they're very close. There are significant gaps when she talks to me whenever she is around or active on Facebook (I don't know the friend). But all the times she's been away my girlfriend had always been overly affectionate with me, I'm not sure what this means but I've got a persistent feeling in my stomach which won't go away and hasn't for weeks, jealousy, paranoia aside.
I notice she replies to me sporadically, and more recently late on a night. She'd previously always be too tired to be up that late, but whenever said girl is around she pops up very late.
There are things she's told me that I've found hard to get over (her sexuality inc), but I've tried my best to overcome it. It still bothers me, all the aforementioned, since it's always in the back of my head, but nevertheless I WANT to trust her but I can't.
When I discussed all of this with her, (during my meltdown), she asked me to ring her immediately, seemed upset on the phone, even though in my own head I couldn't believe it. She asked me if it was about our relationship, I couldn't fathom telling her, I felt guilty, so I just told her it was work related.
A few days later I confessed how I truly felt about EVERYTHING.....the distance, her (the friend), the fact she seems so emotionally absent from me, how communication has dwindled, and about how I'm getting pushed out and feel jealous.
She understandably was upset, though she stead she's upset because she thinks I always seem to re-think on everything she says or does, and that furthermore, she feels no matter what she tells me she knows I don't trust her.
Somehow, I feel this is "displacement" or "projection" at it's best and maybe guilt, I dunno.
Ever since our talk things seemed to be better, though she was constantly telling me she loves me (almost overboard), perhaps out of realisation I was going to finish it all. Since, she did mention she thought I was going to end it, and has said numerous times she doesn't want me too.
I dunno what to think or do....we're fine at the moment, but I'm trying to shift my negative thoughts...
