I just assumed that we were hanging out as friends, I'll give you guys the full picture:
We've known each other properly since about half way through January (I knew him before that as well but not as well) and got close pretty quickly and went out on a night with some of our mutual friends and we both got pretty drunk and went back to his flat (its really close to my own flat) but he was like you're too drunk to go home, just sleep in my room' and so we ended up sharing a bed for the night
That didn't really make anything awkward between us but since that night, we've spent a LOT more time together and have been up till like 4-5am together at least 3 times a week. My friends have said that he's been staring at me more and more recently and he's become much more keen for us to hang out and sleep over at each other's more and also go out to dinner and stuff. He also sent me a long paragraph around 5 days ago just saying how happy he is that we met each other and how much he appreciates me being in his life
I personally didn't think this was anything more than a platonic relationship but my friends seem to think he may be into me, like I do have feelings for him but I won't actively do anything to try make us work and am very happy keeping it platonic but recently he's just been acting slightly more caring/different than he normally is
