Who said you were a perfect husband

I get so sick and tired of being everyone's joke. A few years back my husband B. cheated and he paid for it he was hospitalized and got me a new car. He says he changed his ways. But my sis husband C. Every chance he gets adds in a commit about how B. cheated. Like at least I didn't cheat on your sis. He has done or said things, like he would He thinks that is okay as long as he doesn't go through with cheating. Or just tonight he mentioned that my husband might have other children. That really hurt me. Because he could have other kids and I don't know. But that hurts me because I have to deal with this for the rest of our lives and I don't need to here it from a man who doesn't even support his own wife. C. Needs to get a job and think of his wife only. He needs to stop hurting her feelings. She's a nice hardworking woman who deserves a great man. C. Needs to prove that he's the great man she loves so much. I know my husband B. Has messed up a lot. But love is suppose to be unconditional, so I adore him with all my heart and don't know if I could live without B. He's not perfect in anyway, but C. Needs to understand that he has a lot of issues also. I just needed to get stuff out because I'm hurting and I have no one to express myself to.
