How Do I Leave Him?

He is not physically abusive or anything like that but he has a lot of anger issues and I try my best to deal with it and work through it but I can't put up with it because I am 5 months pregnant and at this point I just want to be happy with my child. I do my best as a woman in this relationship but I am emotionally exhausted because his anger gets the best of him. He has these tantrums and outbursts like a little child. And I am on the receiving end of that. These days I'm just quiet and I listen to him vent and go on but I'm tired. I'm already stressed because of other things on top of being pregnant and this makes it no better. I am truly just numb to it all and I'm ready to find a way out because I know I'm not a bad person and I don't deserve this. He is not a bad person either but I can't take him not being able to control his anger, I truly feel he needs anger management I also needed it at one point in my life and I've come so far. I know he has a lot of deep rooted issues. Do I stick it out or What do I do?
