I know this has been a hard time for you. And it is hard to resist the temptation to "blow".
We both know your H loves to push your buttons, but hang in there and keep validating, showing some patience. I wish I could give you a big {{{{hug}}}}.
You are truely an inspiration to all of us here! But the Lord is there for you and your faith will get you through this. Satan will pull out all the stops here. But you are doing a wonderful job of ignoring him.
Your H is just acting like a teenager; being selfish and playing his games. When your H says he goes to the OW, are you sure he actually does? Or is he just trying to stir you up? The best thing is to do what you have been doing.
Pray, validate and show utter patience. Go back through your threads and find that there are many times that your H has shown baby steps, times when the patience has paid off.
Don't dwell on the bad times, just vent here and move forward. List the baby steps and there have been many! And keep going back and read them.
Your H is just slow and this all will take awhile. Your H's biggest step was to come back home. I think you need to remember that he lives at your house now, not the OP's. Your H knows deep down what he is doing is wrong, but the OP is just an affair, affairs are not meant to stand the test of time.
Your H is on a rollercoaster, he is confused and messed up. Keep showing him that you will be the right choice. I don't know if he will ever grow-up, but he will hopefully get through his MLC, at least I hope he will.
