Boyfriend refused to let me give him a blow job

Ok so Ive been with my boyfriend for 8 years, I never wanted to give him a blow Job before, I don’t really like it, anyway, last night I went to do it to him and he said no and pushed my head away, he said he don’t like me doing that stuff, he said he would never kiss my lips again if I did that, he don’t kiss me anyway, hasn’t for a long time!! Just thinking if he’s slept with someone else
