My two girls are 2 and 3 years old

Reactions in the past have me been screaming crying begging shouting and made empty threats. When I found things out, he never seems to stay with on woman but when he is seeing someone it will be for a few months and at the begging his attitude is nasty.

But now he thinks I don’t know about his infidelity but I do. I stopped reacting and he has tried to provoke me for a reaction and I didn’t fight with him. But the other day he was sure that I would fight him as he came home with a love bite and said it was a rash. I have done my best not to react because the fights affect me and my children more than they affect him.

But me not reacting to him has made him feel insecure about me he checks on me and accuses me.
Also I have been married for 8 years but he became really nasty when I was pregnant with my first child and things have just gone from bad to worse in the last 3 years

Thank you for your response I appreciate it.
