Need advice...

My husband and I have been married for 5 years and have 3 kids.. I'm 8 months pregnant at the moment and our relationship couldn't be worse. He's a very controlling man wants me to stay home all day, keeps track of what I'm doing, controls who I talk to, blocks my guy friends on my social media, has a really bad temper and screams at the kids and I when push comes to shove.. he's a great dad and husband but has all these issues with anger and trust has never trusted me in the 6 years we have been together... I've never cheated never thought about cheating I'm am 100 percent faithful.... but I can't see spending the rest of my life paying for something I didn't do.. my kids don't deserve to be screamed at because he can't control his temper. He's given my son anxiety over his out bursts... I've made excuses for him all these years but now that I'm having our fourth and last baby I just don't know if I can keep going through this... he's very loving and caring brings me flowers rubs my feet and back every night I know he's got a good heart. It's just this dark side that I can get away from.... what do I do?? I'm about to give birth... and have no where to go, but I don't want to stay with a man for those reasons?? I love him but I'm very lost and broken on what I should do.... please help any advice
