Search Results: make her fall in love

So there's this guy i text with, he texted me first and mostly does. But, he disappears in mid conversation. He was also gone for 2 months. But he just always comes back. And it hurts so much when he disappears. I get depressed, crying all day and stuff.
So me and my friends, came up with two conclusions.
1. He knows that i like him. And he thought, 'oh! This girl likes me! Must make her fall in love!' and is using the toxic technique. Just for fun
2. He just does whatever he feels like not regarding what i will feel.
Ps: i asked him why he disappears and he said, 'sometimes i just don't feel like to be on social media'
But he's online forever.
So... Isn't this just another way of saying, 'sometimes i just don't feel like to talk to you'?
So for the first one, I've been thinking this forever. But, when he talks to me, i just brush the thought off. Because, he's so nice, so clean and everything!
Also, i would've known if he was actually doing that right? While talking, i would've known something!
So i think It's rather the second one
And i also want advice on what i should do
Pps: i never told him I'm in love with him
Please comment what i should do
