Appropriate reaction to me forgiving him???

So I caught my husband of many years almost step out of marriage

The last 10 months have been.....rough

So I wrote him a letter that took me weeks to write out

It outlined what I was forgiving him for, what I want in the marriage, how the marriage would be terminated if he did any of the following things I had listed and I loved him 

He instantly got very angry and said SEE things. Never ever ever ever ever stop shut up about things that I’ve done we’ve discussed things so much I’m tired of it

I said what? Now my feelings are hurt I spent weeks writing that out

He said so what just stop if you don’t we are divorced indefinitely

I said I’m choosing to forgive you so I’m lost? You are being so negative

He replied well if you would shut the fuck up you would’ve heard the positives but never mind I’m not going to tell you now

I was crying I was hurt I felt I did something wrong

So I said fuck you and fuck forgiving you

He replied ya see what you just did is weird to me I’m done we are out
