Search Results: talking to crush at school

So me and this boy (I’ll call him Josh) were talking for a few months then a week after that we started drifting, but then one day he FaceTimed me and we never did that before. So I answered and we talked a lot, and it went from FaceTiming once a week to everyday. One day we Fted while his cousin was over and he was pretty chill. Keep in mind that josh told me that he tells his cousin everything. Anyways his cousin thought we were dating and occasionally he left the room saying “I’ll leave you two alone...” and “you guys would make a cute couple” and at one point he asked if i thought josh was cute and i said “he’s ok” but when josh’s cousin asked josh, he said “yeah I think she’s cute”. In our classes together he started sitting besides me too. St the time I gave up on my crush bc I felt it was better we be friends. then yesterday, he called me names like honey and coupley names and I responded cuz ik he won’t call anyone else honey, and then My friend got so shocked he’s like “YALL ARE DATING WHAT” and we’re like “noo” and then I caught a little bit of feelings again... after school tho we fted like normal and at one point we talked about crushes (another usual topic on our calls) and he said he misses his ex (my cousin) and that he started to like a girl in our school. So then I assumed I was in the friend zone and we started talking about hot celebrities n he was fanboying over Ariana grande (it was nothing new so I was used to it) which made me lowkey jealous but anyways, I never told him about my celebrity crushes so I started to tell him about them and he got really quiet, stopped showing his face to the camera, then he just ended the call... in that situation it felt like it was jealous but I don't know. We even talked about our dating standards to each other and even though he had a really long list, most of the requirements actually applied to me. So I’m a bit conflicted? Does he like me or no?

So, first things first, I have a boyfriend and I really love him. It's just that distance between us is 300 km and we get to see each other every two or three months for 2-4 days.
But recently I have been talking to this guy. We go to the same school and to some of the classes. But I never actually thought of him. And one day he comes to me and just randomly talks about things. So we have been talking for a few days. And I like him as a friend. But lately I've been feeling this weird feeling like it's some kind of a crush. I know it's temporary, he's more like a new toy for a kid, so soon it'll go away.
I didn't say anything to my boyfriend about him, one day maybe I'll say. But what if that boy feels something more for me? I mentioned to him that I don't want anything serious with him, just friendly talks and walks and he said it is fine. But what if not? Could he use me one day?
