Is it my time to move on

Me and my boyfriend have been together for three and a half years and I feel as tho nothing is coming from this. I’m moving forward and he is digressing. I’ve voiced my opinion about wanting to get married and have kids that’s what I really want. But instead all I get in response is I’m not ready or I want to finish school(which he’s currently not in school) and get a great job. He’s made me take plan b before which made me feel like a complete home. And it just hurts bc. I’ve worked two jobs l, taken care of this dude when he was doing nothing but going to school. And hurting me, he had got shot I nursed him back to health. I just feel like I’m being used and he’s going to get him self together and realize he doesn’t want me anymore.

He has a kid and been married from his previous relationship none of the factors he gives me was an issue then, yet he claims it was forced and she proposed to him, whatever the case may be she still got a ring. And I’m getting played..

The reason I’m coming to y’all for advice is bc at this point he feels like he owns me, I’ve asked him to leave multiple times and he either gets aggressive or starts acting as if he’s going to kill himself.

Ladies do you have any personal/ or non personal piece of advice to get me through
