I've got two brothers and I'd say try and make the best of it. My brothers and I don't always see eye to eye but we are blood. We've gotten into fist fights with each other and flow 1,500 mile to bail one out of jail because of a stupid wife. Wife's will come and go but your brother is always going to be your brother. Try and fix that relationship if you can.
I'll get off my soapbox now.
