So I am sort of seeing a girl. I made it clear from the beginning that I did not want a girlfriend (or at least I thought I was being clear). Now we have been hanging out on the weekends only for about 3-4 weeks. We usually end up staying with eachother and making out/etc. I mean its pretty much a given that we are going to hook up at the end of any night of drinking. The problem is that at some point I'm hoping to get back with my ex. I am aware that I shouldent have hooked up with her so soon after breaking with my ex, but I was weak and just needed someone. I'm pretty much over the weak stage and I want to explain to the girl that I don't want to hook up with her anymore, but I don't really know how to do it without hurting her. I feel like she is fairly attached and it is my fault because my actions and my words didnt really match up. I told her I didnt want a g/f but when we are hanging out I would be touchy-fealy (grab of the side everytime I walk past her at a party, the little pinches and things you would usually only do with a girl you were pretty in to.) I think the only reason that I did all those things was that I was so used to it since I had been with the ex for 4 years. It was just kind of a natural thing to have a girl that was "mine" so I treated her that way. I feel really bad about leading her on but I don't know how to let her down easily. I do kind of like the girl, and would really like to be friends, but I'm not sure thats possible at this point. I have been putting off telling her for like 1 1/2 weeks maybe 2, not sure. I say things like I'm sick or I just dont feel well as an excuse to keep from hooking up with her. I even started to be less nice to her in hopes that she will just stop liking me, but that doesent seem to be working (I'm not very good at being mean). What should I do?
