Confused

My kids don't like their step father can't seem to get along for a long while now. My husband will consistently criticize my children, keep telling me that they will not do well in this or that. My kids lowest 76% grade average, other kids are doing much better. The counselor said he is absolutely emotionally and mentally abusive.

My kids state they also hate their stepdad because of his negative all the time and his mean thinking towards not just them and me, also even every day life and because they said they heard us argue many times about these things. My kids say he is very judgmental that he feels that everything is me and them. He tries and makes me feel like am not doing a good job when is angry. The kids and some of the other family tell me to leave him for the mental sake of my kids and I. His own family has told me to get out for the sake of all my children's futures and mine, too. He can't hold any sort of relationship with anyone and I pitty him for it and try to stick it out. But the more people that tell me to leave him lately the more I get confused. Heart says one thing Brian says another. I'm 37 and so confused what to do or not do. Is everyone right I'm just blinded by love? I'm so confused.
