Help me What should I do?

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

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

for the money or for the jealousy, dont

basically many factors, but its up to you imo

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