<human>: Condense the text into a few key points

Me and my ex boyfriend have happily been friends for little over 3 months now, and have been skyping every night before I go to bed. We laugh and talk about random things we see online. He begs me to stay up later with him. Last night I kinda got a hint that he was into me again but I didn't mention anything about it.

This morning I was off school and he went to work but when he got back he accused me that I was the reason his "best friend" moved away (it definitely wasn't.)

Also I have been quite upset lately because I kee having flashbacks/nightmares of when I was being molested (only he knows and I guess everyone here knows to) and then he dropped the bomb that he needs to "put up with my sorry ass" and the only thing I talk about is being molested or being depressed. I haven't brought it up in three months, and I needed someone to talk to. 

I haven't messaged him back since. Is this behaviour normal? Should I wait for things to cool off and try being friendly again? Or just cut all contact and run?
<bot>: Ex BF accuses me for his friend moving, and told me I constantly talk about being abused, not sure if he still wants to be friends
