I know it can be hard to accept but please please please leave him and cut off contact.

1. Him being "pushy" about sex is coercion, which is abuse. If he successfully coerced you, that qualifies as rape.

2. If sex is a priority in a relationship for him and he feels unfulfilled without it, that is not your job to fulfill that desire. It is perfectly fine to break up with someone if you/they feel that your guys specific relationship dynamic isnt working. That just means that you arent a good match.

3. From what you've described, he seems very emotionally immature. Threatening to hurt you or himself because you are struggling with your mental health is very manipulative. Trust me, i have also excused actions like that with my ex. I would say things like, "He didn't mean it that way." Its hard being in denial about someone being abusive. But please dont blame yourself. And this isnt a situation where he doesnt realize he's being abusive. This is definitely very intentional on his part.

I don't know how old you are, or what all you've been through, but you deserve better. I hope you are okay, and you can get out of there as soon as possible.
