<human>: Skip to the last paragraph for the question, the rest is background.

We've been together for at least five years, though most of that has been through high school. Now, with me going to college and holding down a job, and her just barely holding onto a job of her own, things are different. She's still a good friend, but I don't know if I want to stay with her.

She's become even more blunt and stubborn than before. She doesn't care about preferred pronouns and names, which is a big issue since I hang around with a lot of transmen/women. She's rude to my younger siblings and kids in general. They may be little snots, but it's really not polite, to the kids or parents.

For the longest time, she said she was going to college to study English. I found out the week before the semester started that she didn't turn the paperwork in on time. (she could've gotten a ton of grants and scholarships because she's a first-gen college students and comes from a low-income family) She managed to get a job as a hostess at a fancy restaurant. She works one day a week.

We talk a few times a week via Skype. I voice chat with some international internet friends more often than we talk.  She makes no effort to come visit me or hang out or plan things, it's always me suggesting something. Whenever we hang out lately, we just kinda stay in the same room and do our own thing. She doesn't want to go to the movies or arcade with me. She has trouble keeping up with me at conventions.

This is our first relationship. We've never been with anyone other than each other. I've thought about it before, but now I'm really considering it. I realized one of my biggest things against breaking up was "how the hell am I supposed to date new people when I have a defective gaydar". That made me think that, maybe, I need to mull over this a little more.

Can you condense the text into a few key points?
<bot>: Not sure if I should move on from high school sweetheart. How do you know when to breakup and see new people? How do you do it? How do you move on? How do you stay friends afterwards?
