We are all here for you. Unfortunately we all share your pain, too. GWH is correct, divorce may mean a new relationship between you two, but that's what it will be - a brand new start from the beginning. Someone on here once told me there won't ever be going back to the old R, but a new one is possible. I know that isn't what one wants to hear, but false hope is even worse.
I'm not even sure I'd take a new one with my W at this point. With all the lies and deceit, it's hard to trust again because it will ALWAYS be in the back of one's mind - no matter how enlightened a person thinks they are.
You have the right attitude, and if he decides to return then that's a decision you will have to make. By then you will have moved on and may not want him back - or it may be the best thing ever. I'm afraid it isn't going to get any easier and some days you'll feel like crawling to him and begging. I miss my W at times, and other times I can't stand even talking to her.
One foot in front of the other...
There are moments in this life when you are so confident in the rightness of your actions, that not even for a second do you consider the option that you might be wrong.
