am I being used for sex ?

I'm with my bf for 2 years, in those two years we went to a public places only for 7 - 8 times maximum. We meet like once in two or three weeks to have sex in the car for one hour and that's it. I mean... shouldn't he miss me ? Or wants to spend more time with me? 
I asked him right now about it and he got angry and said that I think like a stupid little girl !! But damnn I want him to show me that he loves me and cares for me and put more effort but once I try to talk to him we fight because he gets so mad at me!!
Is that normal? I don't feel loved at all, I want my man to love spending time with me. I am starting to get a lack of my self confidence !! I'm so hurt
