My bf (ex bf??) Of 2 years called me some unpleasant words about something he knows I'm insecure about. I told him not to talk to me like that and to have a few days space. We've spent the last 2 weeks texting with him denying he called me anything and I started all of this by lashing out and he was only concerned to which I said it doesn't justify calling me nasty names as if there's a concern just tell me. He then started being sweet saying I was lovely and he can't wait to see me. I explained I wasn't happy with the name calling and I wanted an explanation. He said he'd respond but his uncle had a fall and was in hospital and he hoped I was OK and that he missed me. I left him alone then got a text from him saying he's won and then blocked?? It isn't first time he targets insecurities or block either.
