Oh T, I am so sorry you are here, but this is one of the best places to be.
First of all, did you read "Divorce Remedy?" If you didnt, you really should.
Please, please, please do not do what you have done again. Do not talk about your relationship with your h. Do not cry, plead or beg. Do not snoop and look things up about the ow. Do not talk about the OW. Your h wanted to get out of there as fast as he could because it was all pressure on him.
Now the do's. First, take care of you. Try really hard to be kind to yourself. You need to start living life for you. You will see that we talk about GAL - Getting a life. Find something you love and do it. Go out with friends and your daughter. Move forward in your life and let your h blow in the wind right now.
