What would you do? (( Relationship advice ))

So I'm aware this sounds stupid... but say you were dating someone... that someone stopped talking to a few people after you and that person started dating( note: you work in the same company) and then a few other people in the company started complaining that the person changed and didn't talk to them anymore, but they used to walk all over the person, then there is me, not wanting to be that person that steals other people away... I am not really sure if i should say screw it, it is what it is or ask that person to make things right and to not stop talking to others that they had before me. The way i see it is, i dont want to be that girl that everyone is like " oh its that girl that..." so I would love some advice Reddit and i know its ridiculous. I'm sorry i worry too much >_<
