Bed room issues no idea what to do anymore. đź‘Ť

My s.o and I have been together off and on for 2yrs,lately he’s been saying he’s not horny. We will make out he’ll get hard but will say he’s not in the mood. I got to the point where I broke down crying asking if he wanted to take a break or just break up he said no I love you,I’m afraid you’ll break up with me. He has no problem watching porn I asked him to cut back, it helped a little. Asked if I was doing something or wanted me to change he said no. He said it’s not a big deal told him I didn’t want to be in a sexless relationship he said were not.had sex 3days out of the month not this month. I think he watches porn before I go over to his house so he’s in the mood. I have no idea what to do. I know he’s not cheating on me.
