I agree with this guy^^. Do it for yourself and your kids bro.  Your in-laws and extended family don't have to live it every day. I wouldn't consider anyone outside of my kids and myself when making that decision
		
		
	 
I do agree with that.  I had to wrestle with a lot of this stuff before. 
Also, no one in my family had ever been divorced and a cheating husband was something a woman is sometimes told to tolerate, or wait around for etc etc.
I did hear from my psych that it was normal.
First time I visited my psych she asked about any weird behavior from family members.  Any mental illnesses, any black sheep of teh family etc.  I told her, "Well, my sister cheated" because I was a noob and as far as I knew cheating was something people did when they were really fucked up!  She laughed and told me (I didn't have enough life experience at the time): "cheating is normal.  It happens to a lot of people who don't have the skills to stay married a lifetime.  It's not something a relationship can't handle if you have the skills to deal with it."  
I do believe that's true.  Its just that without help, a lot of us either need help trusting, forgiving, dealing with meeting our own needs, or expressing our needs etc.  A million reasons someone could turn outside of a relationship and not be a bad person.  It's a very adult way to view the world, but as we grow older we realize that the world isn't as black and white as we think when we are kids.
