I can't be long....

But some of you may remember me and my sitch... I will update a little more later.
Long story short is ... my cheating H came home.
He is still in contact with OW ... as she is pregnant I half understand this....
But I am having issues...and it's starting mini-fights....
I know neither of us want to live like this....but we both want to make it work....
Advice please?
