Sometimes it makes sense - there is so much to be done that you can't think about anything but your family. But then, when things calm down, and you realize that you are kind of lost...well, I want my W to fall back in love with me, but I kind of realize taht there is not much there to fall in love with.
I notice the "Living together platonically as 'best friends'" in your signature. Would like to let your W know what real love is all about.
On the other hand, the "best friends" part isn't all bad. As for W and me, sex when we have it, is hot (not that I wouldn't like it to happen a little more frequently), but I am struggling to gain her trust back so that she will talk to me about what is going on with her. I would love to be her best friend.
If only your W understood what a gift it is for her H to be her best friend!
Keep on keepin' on!
Think about it...if you met a potential mate who was nothing but a bundle of needs, would YOU be attracted to them?
