Some people enjoy driving and being by themselves. I get that, especially if you can't tune out everyone around you. For me, Metro is faster than driving from MoCo and best opportunity to relax before my kid goes to bed.

Just a prank sticker a random traveler put on. My kid got them in his Toca Box once.

Yes, some people have that as a boundary. It's OK for you to be offended and not want to be with someone who doesn't feel the same way as you.

You're allowed to find it gross, and not every guy likes it (or every woman hates it). That said, what are you looking for here? So you want to ask him to leave the room when his friends talk about it? That's an impractical boundary, and at that point it somes more like an issue with him as a person. Maybe you are not compatible.

Yes, it's a horrible idea. You're holding onto a version of your relationship that is dead. You're not making connections with your current or new friends because you're holding onto him. You're keeping yourself stuck in the past and putting an idealized version of him on a pedestal. You need to cut him off and move on. Consider therapy if that's an option.

You go to your dream school. If the relationship lasts, great. If it doesn't, you didn't waste an opportunity for someone you're are barely in a relationship with. You should respect her enough to let her make the same choice.

It would be more than reasonable to ask him not to share that information with you.

Here comes the sun, doot doot doot doot.
