Yes, you are going to make it! I am so sorry that you are feeling so sad. Honey, your h is the one that broke the marriage vows and went outside the marriage to seek the attention of the ow. You were the strong and caring wife who took care of the home, children and your h's every need. You did absolutely nothing wrong. Your h is a broken man and you can't fix him.
You didn't do anything wrong when it came to DBing. You did everything the way you were suppose to but, he made some really bad choices that affected all of you in different and painful ways.
As for your h going to a friend's wedding w/the ow, it shall be an interesting and possibly an uncomfortable situation for the ow. Why? Because people may or may not accept her and yes, they will be wondering what he sees in her, but they will not say a word to your h about his choice. There is no guarantee that they will accept her...some of them may and others will just tolerate her.
As for him telling you that you will regret your behavior one day...please stop thinking about that comment. Don't add more hurt upon yourself. You were depressed and he needed to be there for you as a husband and a friend. If he were the right kind of person, he would have done all he could to be there for you. To say such a thing to someone who has suffered from depression is unthinkable in my books. He certainly didn't have a new battery in his empathy chip.
Rouky, feel the pain. Cry as much as you need to and then release it. You will be fine in a while. In fact, you will be better than fine because I know you'll pick yourself up, dust yourself off and continue moving forward. You will become stronger and wiser than you have ever been. You are worthy of someone who will love, cherish and respect you for who you are and your h isn't that person at this time.
I'm sending you hugs and positive thoughts. Please, please take care of yourself.
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.
