So ex and I split a few years ago. It was my decision.
Turns out the grass wasn't greener (I never cheated. Want to say that now. We were a childhood relationship and I felt like I never got a chance to find out who I was singularly without him)
Turns out it didn't make me happy.
We are trying again.
I have been an utter IDIOT. He left himself logged in FB on my phone and I looked at his messages.
This woman who supported him through our breakup.
I knew he liked her. He told me. It never went anywhere.
However he referred to me as his Whore wife to her. That was my name. Ie 'I'm with my whore wife' until we divorced then I was the whore ex wife.
TBH it was when we were breaking up and I can understand it.
But there are messages from weeks ago (let's pretend she is called Anna) where he repeatedly calls her lovely Anna and sends her heart emojis 
He calls her Lovely Anna a lot.
They were very flirty.
But now we are trying again WIBU to ask him to stop talking to her?
I don't talk to any blokes like that.
I've brought it up before and she said they are just friends
Would you be comfortable?
