DS moved in with his GF last year, they had been together a few years both late teens early 20s.
After a couple of months she decided to go home to her dads, no one else involved, both a bit too young. Was her choice and he was devastated.
He has slowly been getting over it and he’s been playing the field a bit. He and his ex are still friendly. She’s been seeing someone else but also tangling DS at the end of s strung a bit, sleeping with him and leading him to believe there is a chance they might get back together (I like her, but this isn’t fair on DS). I advised him to spend some proper time apart from his ex with no contact for a bit. I don’t think he has, but it’s been 9 months since they split.
Today he’s come round devastated because he got drunk at the weekend and slept with one of his exes friends.
He then phoned his ex the next day and told her as he felt terrible and didn’t want her to hear it from someone else (I don’t think he should’ve done this).
She has gone ballistic, blocked the friend and is giving DS a hard time.
AIBU to think that why is wasn’t the wisest move, she doesn’t really get a say in what he does or who he sleeps with anymore.
I don’t see the huge issue but maybe I am old?
