Mimi, sorry to be all in your business, but your husband didn't cheat because of you - he did it as he is inconsiderate. Simple. You guys have a family and 4 kids, and he takes it upon himself to cheat - merely shows a personality flaw in him - not you. But yes, do what it takes to feel good about yourself
I actually as some know lost 100lbs. Thats quite a long road to take, and worth every bit of time, from my perspective you have a short road to go down. Laura posted her newer pics, she should have included her older pics to - she also made a great transformation. Train hard, eat well and go for it.
Lots of drama on this board, but bar none, all the females are supportive and wish you well in all ways, and most of us can answer any questions you have.
