There are plenty of men that would want a woman like you. You are not broken. You are a great person, your feelings are lying to you.
Your self esteem has taken a blow, you will heal from this. Your husband's decision to cheat is not your fault. It is a result of his character.
Your husband is an idiot and he will regret this one day.
X2 Red, seriously.
I wish I had more to offer you in terms of advice but I can't agree more with everyone here.
I can only imagine how much it hurts, how deep down that hurt truly goes. It's like a bottomless pit of emotions and feelings and crap keeps going in and never truly gets pulled out. It's just there. BUT....you have to let yourself feel it. You do, and it's a good thing to get it out and be done with it so you can move forward and find real happiness. I know you won't, but don't let this define you. You are STRONG, you are CAPABLE, and YOU CAN DO THIS.
xoxoxoxox :] I'm here for ya lady, as always. I may be creeping in the background but I'm reading up on this, shaking my head...in awe...of your awesomeness. Focus on the positive. You will start again. You WILL be better than ever.
