Am I wrong to feel this way?

you are not wrong to feel upset. you just have to realize that there is a difference between men and women, physically and psychologically. the whole "friends with benefits" thing works out great for guys because they get to have fun and not be committed or be in a relationship. for girls, something can come from being friends with benefits and guys just don't understand that. i don't think you can be mad at him for not wanting a relationship. that's just the way it is. and if you still like being around each other, then still be friends! but make it clear to him that you won't be friends with benefits anymore, and if he won't accept that, THEN you can get mad ;)
