Boyfriend advice?

My boyfriend & I haven't had sex in MONTHS. the kast time we did it, there was a pregnancy scare & now he won't do it unless we use condoms but he REFUSES to buy them because it makes him "uncomforable" so he says the only way we can have sex again is if I go on birth control which I don't want & I wouldn't feel comfortable havibg sex without condms while I was on it because I don't feel like I'm protected, so he says either that or I need to find another way. I don't understand why it's so difficult for him to buy condoms & I can't even talk to him about this because he gets so pissed & stops talking to me
