Kissing?

My boyfriend didn't want to kiss me this morning, I was wanting a kiss pretty frequently, but then he just stopped. I asked him this evening about it and he said that he likes kissing but it's gross and that its too much sometimes. I just feel like I violated him and I feel annoying and I just don't know what to do. I said I'll stop and that I'm sorry, but I just feel so ugh.

Edit: so i was feeling numb and then this sharp pain just exploded from my chest area my god that hurt a lot i felt it in my toes wow jesus christ
