Is this normal?

I tend to slip into a younger little state when I don't have a love interest.

I've been single for nearly a month and I've picked up buying slime, coloring books, a loom and anything crafty.

This is absolutely horrible for my well-funded adult side.

This stuff was my jam when I was about 10.

When I'm with a guy I rarely go younger than late teens/early twenties. Even if he's not a 'daddy'.

Tell me this is normal, or how to not spend all my money on arts & crafts fit for a pre-teen.
