Am i being unreasonable, please bit of advice?

-I went to my ex boyfriends house last night, slept over, we had sex multiple times, he was saying last night about getting together again, and how much he likes me.. he's going on a lads holiday tomorrow and i said to him, if you shag girls on this holiday i wont want to see you when you come home, and he told me i was being annoying and controlling..

i just don't think it's right for him to do that if we're maybe planning to get together soon.OK, sorry, but 'maybe planning to get together soon'? Then he's right, sorry again. You should not sleep with him. Not until you were sure you're going to get together again.
