As my mom says, actions speak louder than words. My ex did this stuff during our 50 split too. He would shove son on step mom and then take off. I dson't care how much she loves her son, when her kid gets her they will be priority. It is basic human nature. Your ex is showing his true colors you better listen to them. Do the best thing for your son and not him. I don't know how many bad reviews I have had because of having to leave work for child. My ex has never done it. Thank God for my parents or I would have been up the creek many times.
