friendship?

Hello! time for my first post ya!

I have a friend that is pretty close to me and i feel like we are drifting apart from each other and i shall call him B. Just a brief intro, B and i were not in the same class when we first met each other and we only got closer when he texted me (it was regarding another person). It was there when we started to talk to each other daily and he became my closest friend. Of course, it was pretty awkward in real life due to the fact that we only talk to each other offline on WA. After a few months, i started to realise that i grew more and more dependent on him and he was the one that pulled me through some of my problems. We could literally talk anything under the sun, from studies to dogs to friends to movie etc. Soon enough, we probably grew feelings towards each other but we were both unsure about it. Even though we did hint to each other through our text, none of us have actually said it in fear that we only treated each other as friends (unsure if it was a r/s or best friend kind of thing).

Probably after 2-3 months later, we grew tired of each other and when we chatted on WA, we would ran out of topics to talk to each other. After reading Naomi Neo post, it really hit me that when there isnt any fun anymore in a relationship, we will get tired of each other. AND by saying that, i do not mean that i did get into a relationship with B but we were certainly more than friends.... and due the fact that we always ran out of nothing to talk to each other... there was pretty much nothing interesting going on in our conversation now. Im pretty sure looking at the state now, we had already lost feelings for each other and it really made me wonder, "was it the fun that make me think i had feelings for him" and "is it the fun that only keeps a relationship going?"

well i really dont know, all i hope is that our friendship remains the same...
