Choosing the right brother [FM]

Hi there, long time lurker, finally got up the courage to post my story here for all to (hopefully) enjoy

Bit of background, I’m 26, 5’6’’, with brunette hair just past my shoulders and 36Ds, and nurse who had higher hopes at one point in life. I became a nurse on the path to become a doctor, but my dad became sick and I wound up moving back home to take care of him, and that’s when I met Brad (31). Brad was nice, funny, and overall a sweet guy who was there to help lighten the load after a hard day taking care of dad. My dad for some reason never liked Brad, never gave a reason, just didn’t like him. He passed a few months before the world went to shit, but when it did, I was a bit glad I wasn’t back in the workforce, that shit was scary.
