If you like her,
I mean truly, and you’re attempting to make it obvious…
And she ignores you.
DO NOT KEEP TALKING AND DRAW MORE ATTENTION TO THE FACT THAT YOU LIKE HER.
Females are intuitive creatures, we get it. There’s absolutely no need for you to continue to force the idea of a relationship when she’s busy blatantly ignoring the fact that you’re interested.
In fact, her ignoring your efforts is a hell of a lot better than she could have reacted. Ignoring you could be her way of respecting your feelings enough to not go out of her way to crush them. She wants to stay your friend and not go through the awk unpleasant transition of turning it into something else, not because she’d be with you in other circumstances, because that’s probably not true either.
I’m not saying all of this to be bitchy, I’m just being blunt, because sooner or later SOMEONE is going to have to tell you. Might as well be me.
