I agree with the others and yourself...You are ahead
of many right now when it comes to divorce...
1)You are young
2)Your children are young
3)You haven't been married that long and are not rooted to deeply into your marriage.
4)You see him for what he really is and know you do not need that
5)You still see the value of yourself and did not lose yourself in a long, unhealthy marriage.
6) you did not build up years of memories and material things for your future that he can now take away from you....
I could go on and on, but I think you already know all this and you have your answer, you just have to put it all into action now for the sake of you and your children. Fear likes to hold us all back...even unfounded fear that we start to believe in. You know there is something out there for you when the time is right...now you just have to let your heart know this as well.
