I am sorry that you are in this predicament, but please do not accept this lifestyle as your fate because you are financially dependent on him. Living with a serial cheater will be a death of a thousand cuts. Your children will grow up without a mom, because you will be too mentally and physically damaged by the stress to adequately mother them. They will also grow up believing that infidelity is an acceptable lifestyle. Surely this is not what you want.
I don't know if your WH is a sex addict or not (doubt it), and it really doesn't matter. He would need to follow the same very strict EPs for the rest of his life for him to be safe. This means you will have to be with him 100% of the time, monitoring his every move. Or, go through this over and over again.
This is exactly what happened to me.
and I followed exactly the same path you are in.
I did make more money that WH but, small kids, dreading to raise them with Divorced parent...
11 years after, today, here I am... kids are grown and wished I have left. A lazy father and a depressed mother struggling financially, its not the best example for kids.
Yes, my WH said and did almost all the right things. All this time he kept saying how in love is always was with me. how he wanted us to grow old together, how we would retire to our little farm house... intimacy always great.
Now... I find that at least for the past 5 years, while I worked hard to build his company, I find he has been in affairs the whole time, while I even worked two jobs to support family and the company.
Yes, he went to counseling on his own. So now he is following councilor that he needs to be independent. That he has to pursuit his happiness. So he is living the single lifestyle looking for the perfect wife.
He just became better at hiding affairs.
