My ex and father of 1 year old dd doesn't have his own place so when he sees dd at the weekend and I occasionally have a night out, he stays over and looks after her at mine.
Last night I went out and had a few too many resulting in me sleeping with an ex friend with benefits and I stayed over and returned this morning.
My friend can't believe that I'd do this because it's clearly hurtful for my ex. But what can I do if he doesn't have his own place? I feel bad now and I'm not sure whether I should or not. She's kind of ruined my happy little buzz I had.
Was I being unreasonable?
