GIRLS HELP A GUY OUT: IS IT SO WRONG TO MOVE ON?

My ex and I have been broken up since summer, but we vowed to stay friends. It worked, for a season. We eventually became friends w/ benefits and it was really wearing on both of us emotionally. So we stopped all that bullcrap. Well we were doing good for a while and we slipped up and it happened again. All of that doesn't matter though. What I need you to know is that we fought...CONSTANTLY...all after we broke up. I grew weary of it, tried to break it off, and she freaked and made me feel like complete and utter sh*t b/c she "has a lot going on right now and doesn't have many ppl to rely on." She used that about 2-3 times since we broke up. Basically I wasn't allowed to go anywhere w/ girls (even though I did) and when I did, and told her about it (which was most of the time mind you) she STILL freaked out at me. I have a lot of friends that are girls, and she HATED that. (Bear in mind we're still broken up).

Okay...so we haven't talked much this past week due to school being a b*tch and just everything was stressful in that area. Well last night she started talking about drifting and whatnot, and I basically told her that it was bound to happen at some point and stuff and it just escalated into this HUGE argument about why we should just drift and our friendship end on decent terms instead of me just meeting a girl, going on a date or two, and she finding out about it and our friendship ends on horrible terms. I've told her I have options available to me (girl-wise) and that if I just decide to pursue one, she's going to hate me.

Honestly, I just want to move past everything. I feel like I can't really live w/ her in my life. Am I wrong for this? Is it so wrong to move on w/ my life?
