Please help me... Why are people such inconsiderate jerks even family? I should say especially family...?

I will try to shorten this. I do anything my mom need from paperwork to doctors. and recently due to my persistence we found out she has a total blockage in her main artery to her left leg so today was surgery day. I have six other siblings and I am the youngest. Well five of the six were there. My brother is one of those guys who likes anyting with a hole AKA a shovinistic pig! And he was talking about his many women and how they go back with thier abusive ex boyfriends and dump him. And I hear this stuff over and over from him. So I said he just likes and is attracted to that kind of girl/ drama. And he comes back and throws in my face about an incidentwhichh happened 5 years ago. I broke it off with an emotionally abusive guy and he was so pissed that the psycho came back with vengeances. Even though he was sleeping with a friend of mine. He aulted me and I had to be rushed to the hospital and came with in millimeters of killing me and left me with 47 stitches on my face. A few months later I met an incredible man and he helped me through the emotional roller-coaster I was on. He is now my husband and best friend and most of all we are excited to say we are expecting in April:) So I definitely moved on and started a whole new chapter in my life. But it really bothers me that my own brother has brought this up and thrown it in my face twice now. He told me that I have no room to talk and that I was in an abusive relationship and so I am just as stupid as all the girls he meets. It bothers me that I try to be the best I can be and live my life because I almost didn't have it and all he can bring up is this awe-full moment in my life. I know all you are going to say not to let other people bother me but this is not just anyone it is my family, my brother, how can he bring up such a hurtfull thing and feel nothing about it? It really makes me feel like crap and I don't even want to consider him family anymore:(
