my boyfriend doesnt want to buy condoms anymore?

so we havent used condoms in like 10 months.. We been together for 2 years..I havent fallen pregnant yet so thats a good thing BUT he doesnt want me to get pregnant yet So i think its weird that he doesnt want to wear condoms anymore. He pulls out , but i told him yesterday that he should buy condoms for us cuz i want him to cum in me but of course in the condom because when he pulls out he puts it all on my stomach and it gets sooo sticky...😐so with that being said. My question is why doesnt he want to buy condoms?? But whats to just pull out ?? Hes 25 and im 22 we both go to college and have jobs so i dont want to get pregnant but i cant afford heath insurance to get me some birth controls. The iud. Should i buy some condoms myself to put on him ? lol
