OK,

So I met a girl about a month ago and we really hit it off, I slept over hers but we didn't bone.

Just over a week after I met her she went on holiday with her fuck buddy. She told me about him and that she'd break it off with him if she found someone for a LTR. I was OK with this but obviously cautious about the situation.

So she goes on holiday, I end up banging a friend that week (girl on holiday knew and was cool about it as she was doing the same). I also had a cheeky date too with someone new but it wasn't great so that was the end of that.

Now before she ges on holiday she says abvout us going exclusive when she gets back, I was hesitant but as we got on so well and met up 3-4 times in the two weeks before she goes on holiday with fuck buddy, I agreed to it.

Now when she gets back she asks if her and her fuck buddy can have one last shag, of course I put my foot down and tell her this isn't cool. She doesn't do it (Humm f course).

Now, over the past two weeks we hang out, have sex and it is revealed that she's quite in love with the fuck buddy but he doesn't want a relationship and wants to remain playing the field. She wants a relationship and knew the deal with him but is having a hard time getting over it.

We have sex, sex is a bit piss poor but I think ok, this is new she still has feelings and what not.

Now go to last friday and saturday, I find out she had sex with him on both days by her telling me over the phone and her saying she's sorry when we said exclusive. She was drunk when she fucked him. Now we've known each other about 6 weeks, tossed around exclusivity but I know she had feelings for him and that he meant a lt.

What I want to know is was me meeting her with the prearranged holiday just bad timing and I fell into a shitty situation or is she a cunt. I took the fuck buddy holiday as bad timing and the fact he meant a lot to her (personal reasons), but she is a great person and when we met we just clicked.

She wants to date exclusively now (she broke it off for good with f buddy last night) but I don't want to fall into the trap of feeling used and feeling worthless.

What do you guys think?

TLDR:

New girl had fuck buddy holiday right after we met, she was pretty much in love with him (they'd been seeing each other 4 months) but wants to see how me and her go. Her fuck buddy doesn't want to commit. She recently had drunk sex with him, told me she was sorry and has told him they're not seeing each other. Did I just meet her with the shittiest of timing and she had crazy emotions, she told me she's felt very confused lately.
