Hi Rock Bottom,
I'm sorry you're having such a tough time. I agree with Karen.....it would be best to get away from this man if at all possible. Being with someone who mistreats you, whether it be by physical or emotional abuse, is a terrible way to live. And cheating, in my opinion, is a form of abuse. I hope you don't think I'm being harsh for saying this, but the handwriting is on the wall, and it is extremely unlikely that this man is going to change his behaviour. I'm concerned for you and for your daughters, as well, because they are young women and are impressionable as far as the way they view relationships with men. See if there is a women's shelter or women's centre in your area, and talk to them about your situation. It sounds to me like you lived through abuse in your marriage, and are experiencing a different form of abuse now.....and you will need help to deal with this. They may also be able to direct you to resources for financial aid and employment counseling, as well as temporary housing should you need it.
Above all else, remember that you are worth too much to be mistreated by anyone. You deserve more than that, RB.
Please keep us posted on your situation. I wish you the very best.
