Is he over me (he is bipolar and recently started taking antidepressants so now people believe he is

my exb/f of 2 years&i broke up over a month ago, and i am still not over him. instantly after the break up he began going from girl to girl, 4 girls in 4 weeks to be specific, i have been out on 1 or 2 dates since the break up but nothing more than that. we havn't talked to each other in weeks, and he randomly blocked me on IM, which is really weird.it seems as if he is trying2do things just2get my attention or2get me2say something2him.&he unblocked me just2look@the pictures in my profile(even tho hes already looked@those same ones twice already,& he doesnt kno i can see he looks@them),then he blocked me again so i wouldnt kno he unblocked me i guess?&then he IMed my twin sister(who he was also very close w. but not nemore since the breakup)&old her how he misses her?just a few days ago he unblocked me&he looked@my pics the sec.i put an away msg up.it seems like hes going OUT OF HIS WAY 2 try&hurt me,which makes me wonder is he over me, or is he just trying2get me2think hes over me?

You are obsessing over this. He could just be unblocking so he can show someone else a picture of the person who won't get over him.

He may be a little indecisive about what to do next, and how to handle things, but I think you need to get over it. I know you still care about him, but could you really live with this kind of behavior? What happens if you got back together and he started acting like that about somebody he's dated in the past month? And maybe he just misses the friendship he had with your twin, but is afraid to continue the friendship or go on to something deeper because of how YOU may react.
