Breakup. got blocked but unblocked?

[Thump]

Short story short. I went out with this girl for a little over 2 years then got dumped for reasons unkown. Well she said its her and shes too busy and that she needs to work on herself blah blah blah. Well like an idiot i just kept calling and crap. So eventually she blocked me on everything facebook aim twitter. Then went ahead and changed her number etc. So anyway last month i noticed i got unblocked from her on aim. Then twitter. Tonight i check my inbox and i see that i got unblocked. Anyway it sorta like made me freeze. Does she want to talk to me or something? Is she having second thoughts? I can't stand false hope it drives me insane. The past 2 weeks shes been in and out of my dreams. I cant get her out of my head. I have been trying desperately to get over her. Other women, binge drinking. Sex with a whole ton of different girls. But still shes in my dreams. Sorta doesn't go away? She broke it off at the end of may! Its october now! Shes emailed last month and i replied but nothing back from her. She was just asking how i was doing etc etc. Our 3 year would have been a couple days ago on the 15th. Maybe she was having memorys? Idk? Im lost
