Haywire, couple of things: stop talking about things you don't understand.
Ask for info; answer questions you are qualified to address, and leave the rest alone. You don't actually *know* the people you've 'met' here....it's an internet forum!
Next, you will have more credibility if you take some time to phrase your questions in a way that makes sense, and lay off the exclamation point. There are other punctuation marks.
And OG2 and the rest are right, and you, my dear, are wrong. Your cheater is a cheater and womanizer, unless you're a guy...then he's just a cheat. If he will break his vows to his wife, and you will break your oath to the service you contracted to, then you are both in deep dark trouble starting out. You are simply in denial, and I am guessing (as an old lady still in the first marriage I promised to commit to) he is using you.
I would love for you to come back in fifteen years, and tell us all in a well-thought-out and articulate way, "I told you so." We will be happy to congratulate you.
Until then, your legal advice is: you are contemplating breaching a contract. You have no legal standing to do so. There you go.
