Raising step kids is a difficult situation, can be very rewarding, but you are the stepdad, kids may love you more than their real dad, may not, but a man has to adapt to the situation . Also the dynamic of being married to a woman with children not sired by u can be a complication between u and your wife. No man has a reason to abuse children as Mrs La described or a woman. But the wife needs to get them kids outta that situation real quick and in a hurry. For their sake and hers. And don't forget, those kids are learning behaviors, behaviors that ain't gonna be good for the boys as they grow up and get married or the girls who , as stated, may find themselves married to the same type of "man" bad situation for all involved, it sounds like ,Mrs. La,, I hope she is getting some help
X2 AND AMEN!!
