So sad....

So Ive been with my boyfriend for a year now. He used to be so wonderful until recently. He's done some things that I guess canbe considered emotionally cheating and it made me really sad. He refuses to have sex with me even though I'm on birth control and he won't listen to me when I try to ask him to at least sext. Whenever I think about not being intimate with him I start crying and (this may seem lame) but when I watch porn I cry too lol. Idk what to do, I don't wanna come across as a sex freak (which he thinks I am) but I wanna share these intimate moments and it's like I'm afraid to ask again...any advice?
