Im 3months pregnant and So asked me to get a abortion scheduled Monday

He says he can't deal with my attitude and he doesn't want to be with me anymore and he has 500$ for me to get a abortion. I'm very sad because my pregnancy has been nothing but a strain on my life I've been fighting through morning sickness and keeping my job and staying in school its been hell now this??? I just hate myself I really need advice. I can't hurt my precious baby its not a bean anymore
