I Don't Believe in My Girl Friend

I don't believe in my girlfriend.
About a year ago, I started dating a girl, and I really enjoy her.

She genuinely loves me and has no strong feelings for anyone else, as far as I'm aware.

However, I get the impression that she finds it difficult to distinguish.

between individuals who "might just be friends" and those she can date.

Even when I try to convince myself otherwise, she always finds a way to be sneaky.

like making sure everyone is okay, soaking up all the attention, and figuring out how to get it all.

She behaves differently around some very handsome males for some reason (usually more than me).

The night before, I had discussions with other males late at night.and when men discuss flirty stuff with her.

Instead of claiming she had a partner in response (she didn't participate though? ), she says, "Thank you."

She acts as if there is nothing wrong with that when I speak to her.

in addition to everyone else thinking about "how much she likes me."

although I want to believe in her and am aware that she doesn't love someone like me.64

This bothers me so much that it keeps me up at night.
