What does that mean?
gpt
Trying to control who is eligible to participate in something, like celebrating anniversaries, or belong to a group/identity. She considers herself eligible to participate because she's married, and she wants to exclude unmarried people. A literal gatekeeper would be someone who opens and closes a gate, presumably refusing to open it for some people because they're not allowed inside of the area. The term is fitting here, but overuse of this term will make you sound like the kind of annoying person who says stuff like "gaslighting," "toxic," etc., so don't necessarily make it part of your routine vocabulary.
