...and another thing, Debra--a new affair is always going to be far more exciting than a 25-year old marriage. Of course she is a 10 and you are 6. I think your 6 is pretty good when you look at it like that.
Ise guy is very good, because he sees things from a male perspective. If I were you I would try to get his attention on a thread, and establish if your guy is in mid-life crisis, or start reading.
I know that I would personally try to seduce him into bed when he comes home. Men apparently feel more loving from connecting through sex, as opposed to women who need to feel loving to have sex. This is not a divorce-busting technique, just me. All's fair in love and war.
