Should I wait until I'm not pregnant?

I'm 33 weeks, Almost 34 and have started to realize I really fucking hate my SO. My SO of four years has never annoyed me so much from accusing me of faking medical emergencies, telling me I'm over reacting, having no type of respect for my feelings and on one of those medical emergencies, even stayed on his phone the entire time. Every time I try to talk to him about how I feel, he ignores me, pays attention to something else or just says " it's because you're pregnant". I think I have reached my breaking point and no longer want to be with him. He's very emotionally abusive at times also. Should I wait a couple more weeks or is it time to go?
