Help me What should I do?

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

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

for the money hoặc for the jealousy, dont

basically many factors, but its up to bạn imo

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