Friend with benefits

Mary

Having a trouble the past few days because i think I'm slowly fallen for my friend which is not supposed to because we agree in the first place no strings attached and we remain friends. Also we both know that we have don't proper break up with our exgf/ exbf. We only know each other for about 6 months so far.

I don't know what to do. Should I stop it now since it's not to late yet or should I tell him how I feel and know if he feel the same?
