I think I have feelings for my friend’s brother?

Anonymous
So my best friend’s brother and I have always gotten along well. We have always been more at the acquaintance level though. We text on and off and see each other when she brings me to family gatherings or adds him to a Group FaceTime. When I first met him I joked about how him and I are gonna get married since we’re kinda alike and just get along really well and I love their family. It has been a running joke that me and their family has been in on. My friend has asked him if he finds me and attractive and he said yes. We also call each other husband and wife as a joke. So recently I actually got to spend a decent amount of time with him. He’s younger (senior in high school) and came to tour the college I go to (I’m a sophomore in college). I know there’s a mild taboo about older women and younger guys (the age gap is only like 2 years). So when I gave him and his friends a tour we spent the whole day together and I really enjoyed it. I’m catching myself catching feelings now and I don’t know how to feel or what to do about him being my best friend’s brother and younger than me. Any advice?
