Its all a guess is it not ? I wish there were more concrete ways to measure this madness , but there is not. I suspect my husband was struggling looong before I clued in. In hindsight ( of course ) he was working at almost a frantic pace , he was very very "hyper" and short-fused with his boss and co-workers. He in fact hated a new employee that was hired and I have never none him to even dislike someone. So that was very unusual to have him go on and on about how the new guy was an a##. In actual fact, he was a "alpha-dog" threat to my husband and that was the start of job discontent and bitterness. Anyway, he started an affair in February ( maybe March) and it ended late November . When did I discover it? He was living "somewhere" outside of our home and it was not until late November that I figured it out. So, for me I knew there was an affair days before he wanted to come home. It really is a nightmare remembering that time. I am one of those LBS that told my husband that I would NEVER forgive him, I never intended to lay eyes on him as long as I lived ...and I sure meant it. I proceeded to see a lawyer, make changes at the bank, locked up all access to money, moved everything he owned into garage ( and he was told to come and get it) , changed the locks . And , NO.... not EVER will I talk to you about anything until times ends. SAME DAY he received all this information, he came to talk to me at work....as if I didn't just say I would never talk with him. He refused to leave until I came outside. To make a long story short … he was hospitalized , dumped the OW ( he says he dumped her several days before ) and begged to "fix the mess he made". I guess affairs are just not that exciting when the "wife" knows. I have no real idea. I asked my husband ( a million things ) when he began to feel "unhappy" . He told me he has never experienced "happy" ...ever, in his entire life. Imagine? . He has always struggled . Wow.
