How toxic is it that I’m playing a long game with a colleague who has a boyfriend?

Technically I’m not breaching their relationship
But I am her friend

And I am hoping to God he fumbles.

I’d rather be over her and not care but it’s not in my control.
What I can control is being respectful and cordial

Am I still a bad person anyway?
I hate being that guy
Part of me hates her for turning me into that guy
But I can’t help it. I see her eyes smile at me in the morning and I feel an inner peace I’ve been searching for for years

Even if she was single we’d have a hard time dating.
I don’t even know if she’d want to.
But I don’t sleep well at night because of her.
Been that way for 5 months (since we met)
