Do I have to drop her?

So I'm hoping to get some advice on if I can fix this situation with my SB. We've been together almost a year and in general it's been good.

We are exclusive and it's kind of a SGF type thing. She initially asked for a monthly allowance, low middle xxxx, I trusted her and it has worked out.

Our dynamic has always been that we text daily, meet 1x weekly for fun, and we will meet 1 or 2 other times during the week if she asks.

She's flirty and late 20s. She likes to go out and get attention, I won't go out publicly like that - so I don't too much. She has guy friends, and while I don't like her hanging out with them til all hours of the morning - never any reason to doubt her - i don't complain.

We've recently had a bit of a spat that I don't spoil her though ("my friends spoil me more than you do"). And we didn't speak for a few days.

Now she's come back and said I'm too controlling (I suppose that's true) and wants 2k more allowance to continue the relationship.

I don't have a problem with the cash, but I don't think it will al solve the issue that has her feeling resentful.

Any advice on how to discuss this from a solution oriented standpoint?

I really would like to get us back on the right track (and I know I'll get some flack directed at myself), but I'm a bit concerned I'm just prolonging things.
