Wiseyes,
The sooner you get rid of this selfish, controlling , the better off you'll be. He knows Chrissie's selfish but he can't control her. Really? He puts his own sexual needs before yours and those of your young family? I don't know how many more red flags you need. Some people are just a-holes who care only about themselves, it happens.
Do the best you can for yourself and young family and if you can afford to, avail yourself of some therapy to restore your self esteem before "Chrissie" can damage you any further. Send this pos down the road...
