My bf and I are super-chill and we've never fought, but I gotta say, it's REALLY nice having a soothing long drive by yourself, blasting loud music and singing at the top of your lungs.
He doesn't like noise so by my own choice, I've never played piano or sung in his presence...and I've actually had training in both.
I'd just feel bad about bothering him, but that's part of my personality in general anyway. I'm always afraid I'm bothering people.
I was single for a LONG time (years and years), because I thought I didn't have time and wouldn't be able to put in the effort etc, but I've learned that if you meet the right person, you'll feel comfortable in setting boundaries and being around each other all the time without going insane. It won't feel like work, because you'll feel comfortable enough to not be worried about what the other person will think.
Like, my bf is a super-duper introverted hermit-type and I'm pretty sure I'm the only person he can stand being around for hours. It helps I'm quiet and do my own thing too. You just gotta know yourself, and know what you're willing and not willing to compromise. One of my friends always has these stories about how she attracts awkward guys and I'm just about the point of asking her what's wrong with awkward guys if she's complaining how she's still single.
Not all awkward guys are total creepsters! Usually they're just cute-awkward.
Don't get me wrong, staying single is a totally cool decision. But if the reason why someone is single is because they're bitter, hurt, or jaded, isn't that healthy IMO. But everyone figures out their own life stuff in time...
