PMS - the ultimate relationship killer?

[cableguy]

It'l be our 12th anniversary in August. We have a 7 year old boy, and a 3 year old girl. We've been having problems lately - lot of it is that she feels she married to young and for all the wrong reasons She is very religious, so I keep reminding her that God must have put us together for a reason. We're both thblack sheeps of our respective families and think differently from them. Most of the fights between us seem to stem wheneer I have any interaction with them - she feels she's been mistreated over the years by them mentally.
I read somehwhere online that agreeing with your spouse is one of the most effective way to diffuse an argument, seems to work.........

I stayed up late many evenings reading lookout123's thread on his situation and eventual divorce, that kinda made me think that maybe she's got some type of bipolar dissorder. I've been seeing a councellor since the fall for stress - I've had a few breakdowns since. I've suggested we do the same, and insisted that before we see a marriage councellor, that she see a concellor on her own to talk about hings and perhaps get a difference point of view on what she's feeling.
Meanwhile, my brother is getting married in November, and I know that having anytning to do with my side of the family is going to be VERY tense.
Then again, my family has always treated me like an afterthought, so I wonder why I even bother. After all my wife and my kids come first right?
