We’re not in a relationship, but he has residency of our daughter. Every time I don’t meet his demands (maybe I’ve missed a phonecall, or wasn’t available for a phonecall, or turned down an invite to go to coffee with him) he send me multiple messages in a row, calling me names, belittling me and making me feel like an awful person. He makes 1 rule for him, different for me, it feels like with every conversation I am being tested. If I buy daughter a gift he accuses me of trying to score points with him.. I dont know what to do
