After a 2 years my ex claimed that she loved me and I'm the best bf she ever had but something didn't feel right... She broke up with me and I was devasted, I tried talking to her for a couple weeks but once I saw it was going nowhere and she was acting very cold towards me and I let her go. After a month she started calling me again and slept over my apartment a few times, will hook up with me but won't have sex with me claiming that its going to make things complicated. What do I take from this? Is she messing with me trying to keep me to fall back on? She knows I want to be with her, I just don't get it.
