I can't be with him because it's not good for my kids--my feelings aside, they need a good role model who gives selflessly to them.
Why do you want to blame your kids for this ill-fated relationship failure?
That’s not fair to them and it’s paving the way for lots of resentments down the road.
You are basically saying, it’s ok for him to treat me like crap but not my children. How about you become their role model and get yourself to NO it’s not ok how he treats me that I deserve far more then what he could possibly offer.
