SH, I am here. I see two things here. He calls you when OW is not around. As bad as it seems, at this moment, you are the next choice beside OW. He does not go hang out with other friends, or do some other things and act like you don't exist. That means you are still competing with OW ONLY. It would have been worse if he lives life as if you are not part of his life. Second, for now, ignore OW when H is with you. If you feel that he is wanting your praise, give him extra praise on every little thing. You want to be the "less clingy, happier, easier, nicer person to be with" while OW is still in the picture. Win him back solid first. Then you two can work on the guilt, forgiveness, etc. Talk later. HUGs
