I need some advice as I'm not sure if I should forget about it or not. I don't live with my boyfriend but we have a 5 month old together. Yesterday he met up with a few of his friends and they had a few drinks (he wasn't drunk as he was messaging me normally last night). This morning he messaged me and told me that he didn't know his ex was going to be there until he went. He told me that she kissed him and kept trying to hold his hand (apparently he moved) and that she sat on his lap and he felt too awkward to tell her to move.
I haven't replied to him yet as I'm annoyed but I'm not sure if I'm BU and should just forget about it. Wwyd?
