why is he doing this to me?

[Juji D]

You should tell him your thoughts and sort things. Tell him how you feel. And if he doesn't like you the way you are dump him. The man should respect your decisions.

Dont let him get to you, your fine just the way you are and if he loved you he would accept you for who you are. I could give you thing or two to say to him to try and fix the issue, but if that is how he really feels, which it clearly is then it most likely just wont work. He would always at the very least think about such things when he's with you even if he doesnt say them and be unhappy. You should find someone who likes you for the exact person that you are

all your allegations are right. if he honestly thought you were on a date, he has some jealously issues. alot of issues over all. you can do better. there are many other guys out there.

You are dead on. This guy is a controller, a manipulator. It is a power trip for him and helps him feel better since he obviously is unsuccessful and has low self esteem.
Your lovely figure is fine. He is just trying to make you feel bad to lower YOUR self esteem. Don't let him do it. Dump this loser now.
