Willa, thank you for replying and for your encouraging comments.
Several years back my husband and I went to marriage counseling. The counselor wanted to see him every Wednesday and Friday of each week, and asked if I would come in once a month. Counseling didn't last long.

He felt it was an unnecessary expense and was also uncomfortable sharing "our private issues" with her.
He has admitted that he may have some problems with depression, however, because of the type of job he has, he can't take certain types of medication and continue to work....it's against regulation.
I have attempted to separate from him in the past. We talked...he told me that he can't live without me, and that he would change...and he did, for a while. Then we always seem to end up where we are now...the cycle continues. When my son was younger, it was easier to hide the problems and deal with them myself. Now that he's older, he "gets" it, and that's what breaks my heart. My husband travels a lot which gives my son and I some releif during the time that he's gone. The house is void of stress and tension while he's away.
The really sad thing about this is that when my husband's not in one of those dark moods, he's such a great person. He is soooo charasimatic and charming. Anybody looking from the outside in would never guess what's going on.
As far as living like this for the rest of my life, I don't want to do that, but more importantly, I don't want it for my son. Having said that, I also need to say that my son needs a father. BUT, he needs a father who will be encouraging, supportive, understanding and ACCEPTING, instead of one who is angry, and....
Yesterday I brought up the topic of counseling again. I explained my concerns for all of us and I asked him if he would consider it, I felt like we ALL needed it. He adamantly refused.
I'd give anything if I could make things different and have a normal family that was absent of any dysfunction....for my son's sake.
