3 months without sex

haven't had sex with my boyfriend in 3 months and one day he started getting grabby and teasing himself until I refused, he went to the corner mad and started watching porn, and then sends me this 😞 thoughts on what to do? (my vagina feels inflated and hurts to have sex) & i feel like i have to give him sex in order for him to be happy. Note I also caught him texting other girls from his work thats why i refused to give it up he doesn't deserve it 😒
