made me feel

My boyfriend has never been a very affectinate person (been together for 7 years) and I very much am. I have dialed it down and not take it personal that he doesn't want to kiss, touch, hug, cuddle, have sex, hold hands often. but lately the way that he says no when I try to do any of the above makes me feel like I am a desease that he does not want to catch. how do I lower expectations and change how I look at it?
