Doesn’t mean you can’t reach out to her first. Nothing is physically preventing you. Your pride is getting in the way.

Trust me. As someone who’s done something very very similar (basically the same thing. It’s definitely a trait common among younger ISTPs) don’t let your pride/ego prevent you from missing opportunities.

Well first you should decide what’s more important. Your pride or your friendship with said person. If you value your pride more, cut her off and don’t regret it. If you value your friend more, reach out. Apologize for being MIA, own up to the fact that you ghosted and then let her decide if she wants to continue the friendship or not.
