Don't compare yourself to the OW; as you can read on many of the sitches here, the OP are almost always 180 different from the LBS. Don't know why, but they are.
My only piece of advice, that I meant to leave you with earlier; is to stop having sex with him while he's with the OW. It's counterproductive to making him miss you. Even if you only need or want the physical part; it allows him to get some of what he wants/misses from you without having to recommit to the M. You have to make him "miss" the M.
