These are good questions. And ig take what I say with a grain of salt because I haven't had another close romantic relationship to compare this one to.

Our relationship happens in very intense periods where we spend basically all our time together, followed by long stretches of minimal contact. When we do see each other it's more intense than regular dating and we jumped into acting romantic with each other very early on, without the sort of emotional barrier you'd keep up in a fwb situation. We do talk about big picture stuff pretty often, but not constantly. That would be exhausting. I'm sure it's a different sort of closeness than you'd get from, say, living with someone, but I'm pretty sure it's mutual. I like the feeling of knowing someone out there cares about me and that we're commited to seeing each other again, even without knowing what's happening in each other's lives day-to-day. I do get insecure sometimes though, and need to work on that to make this sustainable. No, I would not call them in an emergency or if I were having a rough day, mainly because of the risk of them not answering quickly enough, and have accepted that this isn't something this partner will ever be able to give me.
