I dated this guy for 6 months and few days before our 7th moth he breaks up with me because he thinks he is a bad boyfriend, is not going to change I am a great girlfriend just not for him, he loves me but not in love with me and should not be in a relationship. I sent him photos through email the day I got all my stuff from his place and didn't talk to him. About 2-3 weeks later he wakes me up at 1:45 am. Saying thanks for the pictures and he wanted to see me. Then he made it clear that he wanted a booty call. Is this part of him missing me? He has already gotten a divorce for 3 years and he has 2 kids.

No this is him waking up wanting sex and he did not have another girl friend in his room at the moment. If he missed you, he would have asked you to have dinner with him,
Perhaps he did not have the money for a hooker and figured you would be free.
