I think I have determined that, for the time being, I can't suggest escalating to anything more serious at this point. She's casually brought up more than once how much fun she's having, as if to tell me "that's all this is". Since we started out on Tinder, I have wisely kept my expectations in check and tbh am glad I've kept quiet until now. Maybe things will changed down the line, but if not, that's okay.
I can't stay in this state forever though, eventually I guess I'll have to say I want something more serious, or to move on. I don't want to reach that point though I wouldn't be surprised if I just keep doing this indefinitely because of not wanting to lose this connection ://
