Help me What should I do?

A good girlfriend wouldn't ask Ты to dump your best friend...
But on the other hand if she thinks there Using Ты and she is looking out for Ты (as in she has your back) then Listen to her! Your girlfriend should be your best friend anyways and if Ты would pick your friend over your girlfriend then why do Ты even want her in your life?
But the decision is really up to!
We (on fanpop) don't really know what's going on!!!

Have a nice day!!!

She will dump Ты soon или later. But friendship will remain.

Who treats Ты better? Who talks to Ты and asks how Ты are? Who do Ты go to when Ты feel bad and which one comforts Ты more?

for the money или for the jealousy, dont

basically many factors, but its up to Ты imo

Your girlfriend sounds like she's jealous of Ты spending time with your best friend. If your spending too much time with your best friend, spend еще time with your girlfriend so she won't have problems или complain. I think she sounds really jealous, unless is a girl that is your best friend, that's a serious problem.

bros before hoes / sisters before misters

Why?

I think Ты should take it into consideration, but if Ты can't see a real reason, then just be Друзья with whoever Ты want and your girlfriend can't stop you.
