Hes proposed to me and is desperate to get marries - hes the one wanting it ASAP. Iv actually been in two minds. So isn't this a positive?
Hang on, do you think he is desperate to marry you because he loves you so much?? Do you think this "proves" deep down that he respects you and will treat you well? You think that you and he want the same thing out of a relationship but you don't.
You want a loving, supportive partnership of mutual affection, trust and respect. He wants a wife to run his domestic life, look after him, obey his commands, put his feelings above her own and make him feel powerful and important. And also to let him keep conducting affairs with other women - after all, he can't be expected to just be with one woman for the rest of his life, can he?
He doesn't respect women. He doesn't even like them. He threw you and your daughter out of the house, he badmouths a woman he professed to desire, he thinks that you should be grateful for scraps of his affection.
If you marry this man, he will continue to cheat on you. That is a given. He has shown you very clearly what he is like - indeed, a big part of your allure as a wife is that you will tolerate him cheating. Oh, you make a fuss and get upset and he promises not to do it again, but he knows you will always be desperate to "make it work" and give him another chance. And another.
Over time, he will tell the prospective other women (and there will be loads of them) that he and his wife have a tacit understanding - that you know about the affairs and don't mind. He'll say that, although you two never discuss it, you turn a blind eye as long as he is discreet. And that will be sort of true, won't it? Because you already know this man isn't faithful to you and you tolerate it, don't you? You'll continue to make excuses for him and state false "lines in the sand" ("believe me, I've made it very clear to him that the NEXT time he does this, I'm walking away and he knows I mean it this time" etc ) but you're going nowhere. And he will keep cheating. So there you go.
Marry him if you want, OP. But be honest with yourself about what you're signing up for.
