I'm going to refuse sex after my boyfriend says he'll be sad if I end up pregnant and have an abortion
It definitely seems as if you and your boyfriend have a difference of opinion here. Could you tell me more about what you're dealing with?
I told him I would break up with him if he didn't support my decision to have an abortion
Having an abortion is a personal choice and ultimately your boyfriend doesn't get to have a say. This is an important issue for many people and it being a deal-breaker for you is absolutely understandable and there is nothing wrong with that. Refusing sex in such a situation is logical.
My boyfriend deserved it. He is a dick and I told him I would give him a blow job if he wanted one.
Your sexual choices are your own. Just don't let others push you to do anything that you don't want to do. It's important that you take care of yourself.
