Samething everytime

Im venting, i already know what to do and im going to do it. Anyways im 8 weeks pregnant and anytime i ask my boyfriend for anything it turns in to an argument. We have been together for 3 and a half years, 2 of those years i worked while he did absolutely nothing but play his video game, he left me when i was struggling but came back every time. In July he left and i was done started seeing someone new but long story short he ruined that.... Anyways i thought since i was pregnant we would give it another try. Smh there's no point i have a new job lined up just waiting for my new eye glasses so i can start been unemployed for 1 month hes held a job for 1 month and acts like i owe him something he calls me lazy, incompetent, and if i say anything about how hes treating me im starting an argument and im a narcissist like seriously! So i suppose that while im waiting for my income taxes and to start my new job i can just suck it up a deal with it then once i have the money i can just leave his sorry ass! Im so fed up with his bullshit!
