It's ok....it's done and out there. Leave it be, now.
You will need to get in control of your heart and your urges while you go through this.
If you look at your H, you can see that he is making decisions according to HIS feelings, emotions and urgings. Does it seem like a smart path to you?
Well, it's not a good one for you to necessarily follow, either.
Journal - get it out in a book. Write letters and toss them.
Let him be and get the focus on YOU.
Instead of words, change your actions. And change them for YOURSELF, not because you hope that he will notice.
I'm going to turn in - remember to take care of you while you go through this. Eat something healthy. Get enough sleep (you may need a sleeping aide if it is a problem - you can't think straight if sleep-deprived). Exercise. Do something that is NOT focused on your marriage or relationship, like a hobby or volunteer thing. Is there anything that you have put off, a passion that you have put on the back-burner over the years? Dust those old dreams off and see if you can make one of them come true.
Rediscover yourself, and you will be more like the person who your husband found attractive long ago.
