Husband’s infidelity

I found out my husband was having an online affair in December of last year. He cut off all contact with her, we saw a marriage coach, he promised it wouldn’t happen again, etc. I just found out he is having another online affair.

I need a believable T that will allow me to stay married to him. We have many small children still in the home, and I do not want to put them through a divorce and its consequences. I can’t change my husband. He is going to do what he is going to do, no matter what I think of it. I need something to replace “I can’t believe he thinks so little of me.”
