What does 'x' mean in a text?

So this guy sent me a message with his name and an 'x' below. His messages are long but he takes a long time to reply (he said he's busy working). If he liked me, he would've messaged me sooner, but then if he didn't like me, why did he put 'x'?

Is it possible he just wants to be friends, or more?
