Out of sight, out of mind?

Just a simple question. "Out of sight, out of mind" or "absence makes the heart grow fonder"?
Which one applies to you more, Geminis?

For me it's out of sight, out of mind.

Example: My ex (who wanted to remain friends) pretty much has down sweet fuck-all in regards to actually staying friends. She doesn't call, she doesn't reply to texts. It seems a huge effort for her to even acknowledge my existance... which is her own downfall because as time goes by I care less and less about her and eventually if it continues she'll end up being forgotten. That's just how I am. She wants to be out of my sight? She'll end up out of my mind...

Out of sight out of mind. I have never grown fonder of someone just because they weren't near me. Probably why LDR never worked for me...
