Found a message on my boyfriend’s phone from nearly a month ago to his ex (apparently she wasn’t nice and he was done with her!). He was texting me that night and everything was going well, suddenly he started getting really nasty, calling me boring etc I told him to text xxxxx (ex girlfriend) because she isn’t boring like myself. So he started texting her (but never told me), she was vague in her answers and eventually ignored him... in his last message he says “love to you and yours always x”. I confronted him and he says he doesn’t remember texting her... that he was probably drunk etc, I told him that is not an excuse. I’m really not happy and wonder what everyone would do in this situation?
