This is something of a second time around for me. About 15 years ago, my H went through a crisis. After he returned home, I, unknowningly teased him about his MidLife Crisis.
He didn't have an affair, as far as I know, but he acted the teenager and did all sorts of really dumb stuff. He was angry and horrible to me and did all the same stuff, but to a lesser degree. He was gone about 4 months before returning and declaring his love all over again-despite his short time away-the process was years in the making-he came back and committed himself anew, complete with a new engagement ring.
Anyway. This time has been way more severe in terms of his infidelity and so forth.
I look back now and see these little fits and starts of a crisis throughout our marriage.
