My boyfriend...

We were having a discussion last night and he said he hates that I call women he may like , such as a celebrity I may say something about them having smaller breasts than me or even if I say it about a local girl that I fear he may like or someone who I think is dressed slutty or whatever. I am not being mean I guess it's just something about my personality that comes out and it's a jealous streak! So he said he only wants me and I have nothing to worry about and the conversation was weird and random. Now I feel paranoid. Should I worry? He says he wants to marry me and I gave never been keen on marriage my first  marriage was abusive so I am just not in a hurry. I have major trust issues, so I know this jealous bone stuff is my fault!
