I’m sorry to tell you this but M&S, while terrible, are not the biggest issue. Your relationship is terrible already. You are young, but you should know that it is not normal to be afraid to bring up issues because you are afraid of your BF. That is emotional abuse.

Further, he doesn’t trust you for no reason and he keeps talking abt wanting to break up.

There is no relationship here worth fighting for. You are young, you will find someone who actually loves you and cares about you and trusts you and values you. I promise
