Oh Brenda, my heart is just aching for you!

I think Tink has given you some wonderful advice. It's up to you to decide how much you will take and for how long. Remember though that life is too short to live with heartache day in and day out. You might also want to seek counceling for yourself, to see why this is the type of man/husband you've picked twice. We all do things, not matter what it is, for a reason....you need to find out why..... so it will never happen again.
I'll keep you in my prayers sweetie....
