I am very happy to read that your eyes are doing much better. They needed some time to heal properly.
As for your xh, wish him well and just let him go. He wasn't ready to recommit to you and repair things. He would have been right back out the door as soon as RT contacted him. He came home because they may have had a fight, but you see what happened? He went running right back to her and this time, he's planning to marry her.
He's not finished baking and he's got a long ways to go before he is.
I can't believe she told him that she contracted a STD from a toilet seat! That's the same excuse my xh used when he got mono the first spring after he left.
Yes, RL, you've changed. He doesn't realize that w/time, everything changes and your changes are permanent and you aren't a push over and believe everything he says any longer. The rose colored glasses were broken the day he left for Russia. Life is good now and you've met someone new and sound very happy. That is what is important...happiness and being appreciated and loved for the person you are.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
