Brother is a jerk!!!

We made some food and had a family gathering in my house, my pregnancy came up and we were talking about how this baby if everything’s okay had to be my last due to this being my third csection and saying how I might get my tubes tide only if it’s safe and we do more research if not my husband is okay having a vasectomy, then my brother in front of everyone say to my husband you can’t have a vasectomy what if you guys break up and you want to have more kids without her and I was so shocked by it I said to stop and that was not okay to say especially since this is our third child together and happily together! I don’t know what to do with my brother anymore, I want family to be together and have my nephews and niece around but sometimes it’s so difficult,even if my brother had problems in his marriage never would I tell him what if you guys break up!
