About a month ago DS broke up with his boyfriend, after this he didnt treat DS very good, he told people about DS’s past that DS only told him as he trusted him to not tell people, and a lot of horrible things teenagers do/say but it did upset DS a lot.
Tonight me, DP and DS2 went out for dinner, DS1 didn't go as he's unwell. We've not long got back and I went to check on him and he's with his ex watching a film as if nothing happened!
WIBU to ask him to leave?
