Hi Penngirl. I'm sorry that you feel down in the dumps lately.
So, you had a good talk about feelings and now your H knows how you feel, but he said that he doesn't know what else to do. You will have to tell him what you need. What words can he say, what actions can he do? Ask yourself, what will be the first sign that I believe my H? Then of course, sometimes only time can heal, especially since you are not completely over your OM.
Have you read 'How One of You Can Bring the Two of You Together' by Susan Page? It helped me with insight about how to look at things differently and promoted having a lot of good will toward each other. I know when I get down, reading something positive always helps. It makes me feel more in control of how things can be.
