Emotionally abusive Christian man---He is divorced but I cannot meet his family or friends and he "hides me"?

flirts with other women in front of me, says that I will never be part of his family and cannot go to any family functions such as grandchildren events from school, etc. I have been with him 7 years and while he is my best friend, he also belittles me from undermining me, etc. He states we are no longer boyfriend and girlfriend, but we are "friends". Even ppl that are friends are included in some of the events he does not want me to go to. He also seems to talk to Pastors and I get removed from churches that are large and connected to other churches and the pastors refuse to speak to me about it. Help
