By just friends, I mean there is no sexual interest from EITHER party and never has been and never will be.
To put this into perspective
If you were at her house, she was alone, no negative consequences in the future and she came out of the shower naked, came up to you and told you that she wants you right meow, you would tell her “no I just want to be friends” instead of banging it like a bad starter.
The fact that you’ve been interested in one to no avail, and the only other thing stopping you from the other one is her relationship status, proves my point.
Precisely. :number1
