Children learn what they live.
Ask yourself what kinds of lessons your daughter is learning about love, relationship, commitment, marriage, communications, consideration, respect, mutuality, etc. by living in the environment of a basically loveless marriage. Then ask yourself why you would want to spend the rest of your life in one when there could be something better for all of you out there. It doesn't sound as if you'll get it under prevailing circumstances. I have a beautiful 2 year old daughter who is the absolute love of my life. My husband an dI never had a reaaly good relationship.
