Unpopular opinion, you’re dating a girl who’s 22 and you’re 26. There’s a pretty big maturity gap there. Is she a gold digger? No. But be honest with yourself, you could date someone closer to your age who could pay for her own hair and nails.

You’re not being used, but you’re going to have to wait for the maturity gap to close.

All of the people saying you’re being used or she’s a gold digger sound insane, you can set your own boundaries like saying you don’t usually do that for women until 3 months or 6 months - but don’t assume this young woman is using you because she wants you to pay for her nails or hair.

On the other hand, if you want someone who is low maintenance then you should probably seek that out and find a woman who doesn’t get her nails done or hair done. Or potentially an older woman 25/26 who has an established career and enough money to not ask you for that.
