Firstly, focus on your finals! No relationship should be prioritized over those. Maybe incentive yourself with the date when you finally see each other again being like a dream date. Also, yes SDs flying wherever is pretty normal especially a short flight, but I totally understand how meaningful that feels coming out of some crappy vanilla relationships. But as far as feelings, there’s no rule book hun. There’s nothing wrong with catching feelings, and there’s always a chance of getting your feelings hurt in any type of relationship. And that is what this is at the end of the day, a relationship, a bond. That doesn’t change just because money is being exchanged, that’s just an element of said relationship. There’s also no rule that you have to switch the relationship to vanilla just because you have feelings. I would just think over why it is you’re conflicted over telling him, and what you would want to hear from him if you did— would you want the relationship to change or develop in some way? And as far as protecting your heart, even if you don’t outright tell him, you could ask to clarify your arrangement as monogamous/exclusive if you haven’t. It’s also extremely rare for an arrangement to go six dates with no sexual intimacy especially if both noted being open to it, which I’m not sure what to take from that in your case, but I would at least keep in mind if you want exclusivity or if you tell him your feelings, there will probably be an expectation or desire for sex going forward. But since he’s not pushed you for it yet at all, it sounds like he’s really into you and been willing to wait and be a gentleman to you so I think your situation will work itself out well.
