Sunflower, know what you mean. I have those days too. Days I really wonder if it is worth it. One thing I will throw in. Seems at lot of us here are in the "parent" role. Something to note is it is impossible to be in the parent role with a person that is an adult. You can only be in a "parent" role with a "child". Someone in a "child" role helps set it up. My H used to accuse me of being mommy (only after OW, BTW). Now he comes over and complains that OW is the child and he is the parent. LOL He doesn't like it, but it has made him see how the child helps create the problem. Taking yourself out of either role is a healthy step.
The other hard part of this is the rejected feelings. Don't go there for you own sake. We are all lovable, worthwhile people. Our Hs don't get to decide that for us. Just because they don't want to be with us does not in any way diminish who we are. Be nice to you right now, you deserve it!!
