Sweet home Alabama...

Give it time. I'm sure you'll have a doppelganger soon enough...

I can't even begin to fathom how that conversation went.

Why did your aunt tell you? Did she want you to become his girlfriend?

oh that's creepy... your aunt is fucked up for saying that to you and compromising your relationship with your cousin. She may have made it up in a really weird attempt to flatter you, or he told his mother something insanely personal and she felt the need to actually tell you. super messed up. i feel sorry for you and your cousin, you should talk to him and you should confront your aunt. she needs to know this is not okay.

Your cousin has issues.

Been there, done that.
