Should I leave?? Help

Hey ladies,

I’m on the fence about my marriage. We got married at 19 and have been together for almost five years. Everything was great at first, but lately he has been really controlling and has a bad temper. I talk to him about it, and he’s 100% better, but we’ve been through this before and he just goes right back to his old ways once he thinks I won’t leave. Should I keep working on things with him or follow my gut feeling and leave?

Thanks in advance!
