I hate to get into my past, I have been married for 17 years to a wonderful man, and he was my best friend, now we are married and he is still my best friend. Before we married, I dated a guy like you are describing. Possessive and jealous, we dated for all most almost 6 months, before I got smacked he told me I ASKED FOR IT, with sorry, sorry, so sorry I will never do it again. It got worse and worse, my friend (now husband) kept saying leave. I kept saying he does not mean it, he really trying, you don’t understand him. I will make this short because I can get really windy when a question touches my heart and sole. I learned who he was one night when I came home late from a night out with my friends and he met me at the door with a baseball bat. He broke my nose separated my jaw, and broke the bone under my eye and left me lay on the kitchen floor. My friend (now my husband) was the first one I called to get help. He called 911, when he got to my home and seen what had really happened to me. I do not remember much after calling him. I lost 4 day of my life lying unconscious in the hospital. This happened two days before Christmas 87, I married my best friend, May 28th 88. I think he felt sorry for me. It was funny in a way because we never had any feeling in that way for one another. I look back now and say he did me a favor, we each, my husband and I found our sole mates.
All kidding aside, if you feel that this man is or can be abusive, LEAVE HIM NOW, and do not do it alone. I hope things work out for you, be safe please.
