I like my bff and i kissed him also

Like i shared before i kissed my bff and we made a conclusion that we did this because of our lust but i did it because i like him so much……rn we are in college and we study together and my feelings are growing for him but he is like i am looking for a girl to date, i need a relationship and i want a girlfriend etc…and sometime i pretend like i am searching for u but i hate doing this bcoz i like him

What if he started dating someone and cone into a relationship what i will do???
