I'm confused You say: First, think about your kids. They "love her to bits" and now she may be out of their lives.
Which to me means don't be so rash to let her go.
Then you say it's a clear signal that I should.
I don't see the difference between possibly being worried about that or being worried about my W walking away again.
I can remember when I was 18 and I was dating a girl. This other girl that I fancied for years beforehand came on to me after we had both been drinking. For a split second I reciprocated the kiss. Does that mean it's in my nature? I guess it does.
I've now known GF longer now than I had before W moved in and we got engaged. She does love me, she tells me a few times a day. I feel it when I'm with her. I've never met anyone like her. If we got married a month ago wouldn't I be told to buckle down, forgive and make it work?
Maybe I need to flesh out what came before a bit more.
She has been there when W has said I can't have the kids. She was there when W accused me of child abuse and threatned to ring the police. She was there when W wanted play happy families by using the kids (even longer story). She was there when W said that I had been sleeping with W behind GF's back. Then I managed to get W to retract that but took the opportunity to bad mouth me. This ^^^ plus me not giving her what she needs in an R would take it's toll on anyone. There are no excuses for what has happened but it's no walk in the park either.
