I will have my kids while she is out at the bar with her friends. I can keep busy for the day and evening, but will be home putting my kids to bed. Once they are asleep, I will be alone with my thoughts. I have my brother, mom, or best friend to call. I will try to lean on them tomorrow when the demons in my head come out at night. I am not prepared to give up yet. Maybe the writing is on the wall, but I am not ready to read it.
Hopefully you can find something to do. Read a book? New computer game? Make yourself a nice dinner? Any friends you can have over to watch tv, play poker or something?
As for giving up....I think you misread what I wrote. I am NOT telling you to throw this away and find a new woman. I AM saying that you can no longer think or act like her husband. The marriage you knew IS over. Your actions over the next few months will determine if there might be a chance to reforge a newer, better marriage.
