You have a WAW. Even if she hasn't actually walked away....it is in her heart. I felt the same about my H as your W feels about you. She does not find you attractive by the way you are acting. I know that it doesn't make sense to you, but the more you pursue her, the farther away she will get. If you will pull back and act as if you are happy-go-lucky and enjoy life......and not be this weak, needy/clingy person....then she will start moving closer toward you. You need to be fun and interesting. You need to become more like the man she fell in love with.
There is a chance that your W is suffering from the proper amount of hormones. The problem is getting her to go to a doctor who will run the appropriate tests. I went for years trying to get help and nobody would tell me anything. At last I found a doctor who would run all the hormone test and found out that everything was extremely low. Guess what sex hormones were? Zero! No wonder I felt like I did! I'm not trying to make all women like me, but there are so many out there who have these problems and have grown used to it and don't realize there is something adnormal. Anyway, I try to tell H's b/c so many of them don't have a clue about that sort of thing.
If it isn't physical, then she could be depressed. If it is clinical depression, then she can't do much about that except taking medication for it. Has she been to a doctor at all? Depression can do a lot of harm to R's and in a person's life. It seems to me that something is going on that would cause her to leave her faith and stop going to church. Did you notice if she stopped doing any other things that she normally liked to do? Has anyone else noticed a change in her?
There doesn't have to be something physical or mentally out of sorts with a W to cause her to feel like you've described your W, but it would make sense that "if" there was something physical, to get that fixed, first.
It would help you to read other posts here on the board. Reach out to others and it will help build your support group.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
