Do I like mental abuse?

I went to a concert last night with my boyfriend. We were having a good time. Well he had to go to the bathroom and a teacher I had in high school noticed me and came up to say hi and asked how i was doing. Well my boyfriend saw that I talked to him and he had a fit because I talked to a guy. I asked him what the problem was and he said he can't even leave me alone for 10 mins without talking to a guy. I told him he was my teacher and that he is 65 yrs old. He said he doesn't care who it is and that I shouldn't be talking to any guys. He says he needs to go work out and get in shape so he can punch guys if they talk to me. He said nobody loves me as much as he does not even my parents. Now the problem is I get turned on that he is that jealous and that he tells me what I can and can not do and what I can wear. I know he's mentally abusing me but it feels good when he does it. Do I like being mentally abused? Is there help for me or am I going to live like this for the rest of my life?
