<human>: Can you give me the gist of the text in a nutshell?

[Sorry for poor editing, on mobile]

Im a 19 f. Living with my 17 yo boyfriend, he's incredibly smart and for that reason he has a hard time making/keeping friends. He went to a counselor for an unrelated isssue. But his councilor suggests leaving me and finding someone more mentally suited to him. 

He didn't like the idea of leaving me. But he liked the idea of finding someone else on a dating site. I left home and stayed the night with my mum for mothers day. I came home today and he said he was up till 3 am talking to some girl online. 

I said i was ok with it. But honestly its ripping me appart. I understand his situation with wanting more mental stimulus via new people, but he wont show me the conversations they are having. 

And just today he said i can't leave the house and helo my mum for a week. Hes worried i might cheat on him? 

I dont know what to make if the whole situation
<bot>: said i was ok with bf making friends on dating site, he was awake till 3 am chatting while i was away.
