I have no idea whether or not her likes me, somedays I feel like he does, other days I feel like its the complete opposite?

At first one of his bsf told me that he thinks im cute and i took it as a joke but then from this week onwards two of his bsf that im friends with keeps mentioning him and involving me with him (asking me if i like him, writing his name on my hand, etc). I was quite happy tbh since i had developed a small crush on him too but then today they suddenly didn't mention him that much and appearently he also went on a date today:)(which one of his bsf told my bsf in front of me) Im very confused rn and i have no idea as to where i stand or what i should do. Furthurmore, i also followed him on insta and he just accepted my request and didn't follow me back:(
