Boyfriend of a year recently kissed an old crush from childhood. She has been chasing him ever since. Doesn't seem to give a fuck about me and is probably gloating that I'm now out of the way.
He says it was a total mistake. That the minute she kissed him (yes, he insists SHE came on to HIM) he knew it was all wrong. But she has not stopped messaging him and trying to meet up ever since.
His family know her and are extremely fond of her. She has begged him not to tell his parents about her kissing him whilst he was in a relationship. They see her as some sort of fucking angel which pisses me off no end right now.
I have told him in no uncertain terms that it is over.
But I can't help wondering if I am overreacting. Is a mistaken kiss such a deal breaker?
Please tell me if I'm doing the right thing by ending what was otherwise a lovely relationship over a kiss.
