So first off, I am 22 years old, female, probably bi/pan.

Up until 3 months ago, I have never been with anyone (sexually/romantically/kissing). I just didn't want to, even though I had a couple of offers from different guys/friends. The thing is, I've never really been interested in anyone, and because I didn't have any experience, I didn't really miss or crave ''dating'' anyone.

So about 3 months ago, I finally met up with a dude I matched on tinder 2 years ago. We have been chatting regularly, he knew all about me (that I've never been with anyone and so on), and he was really funny so I was kind of interested in him as a friend. The meet up went really well, he had a couple of friends over so I got to meet them too, had fun. At our 3rd meet up, we talked about kissing.
He is very experienced with women, calls himself a ''polite fuckboy''. Total opposite of me. He told me he would teach me how to kiss if I wanted to. I told him that I wanted to get it over with anyways. After a few failed attempts (I chickened out like 10 times), I finally let him kiss me. It was fine, but didn't really feel anything. We hooked up on our 4th meet up. This was all in a span of less than 2 weeks.

After that, we talked a lot, and hooked up a lot, he's already helped me through really bad times and knows more about me than all of my best friends combined (I don't like talking about my feelings to anyone except him).

Now to my question. How can you tell if you really like someone? Or if they like you. It seems like I don't really feel things the way others do. If he texted me right now that what we have going on is over, I think I'd be fine with it. I have had a couple of friendship break ups, but they never really affected me that much anyways. But if he told me that he wants to date me, I think I'd be fine with it too. I enjoy spending time with him, but I don't mind being apart, though he texts me most of the time. He told me he has a couple of girls asking him to hook up with them, but as long as ''I am in his life, he wouldn't sleep with anyone else''. I told him I wouldn't be interested in anyone else, even if he ''broke it off'' with me.

Does anyone know what this situation means? I am leaving out a few details, this question already seems too long and illegible, I've also never been on a dating forum like this so I hope no one I know in real life finds this lol.

TLDR: Does spending most of your time with another person mean you like them / they like you?
