Me and my ex went through a pretty horrible breakup, it will be 2 months ago tomorrow. He dated a girl for a couple weeks immediately after, I have been pretty torn up. He changed his phone number and text me a few nights ago and said "he shouldn't have hurt me like he did". He also said he was rebounding. He says he messed up. I told him I still miss him and he replied with "I'm sorry." I am still in love with him. What does all of this mean?
