Help me What should I do?

A good girlfriend wouldn't ask anda to dump your best friend...
But on the other hand if she thinks there Using anda and she is looking out for anda (as in she has your back) then Listen to her! Your girlfriend should be your best friend anyways and if anda would pick your friend over your girlfriend then why do anda 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 anda soon atau later. But friendship will remain.

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

for the money atau for the jealousy, dont

basically many factors, but its up to anda imo

Your girlfriend sounds like she's jealous of anda spending time with your best friend. If your spending too much time with your best friend, spend lebih time with your girlfriend so she won't have problems atau 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 anda should take it into consideration, but if anda can't see a real reason, then just be friends with whoever anda want and your girlfriend can't stop you.
