Aw, Faris, I'm sorry you're so disillusioned. But let your negative feelings about romance just run their course. You can't force yourself to embrace romance into your life again. But, from experience, I know you get down about the seeming insincerity of flower-givers and poets.... and then, just when you least expect it .... "HE" brings you one flower, or writes you a really goofy "Roses are red..." poem, or gives you a little, stupid 25 cent toy from a vending machine and all of a sudden, it's damn cute and you could hug him till he squishes.
Sometime it's the innovative, non-traditional gifties you get that enable a man to break through the titanium barrier built around you and win your heart. And usually that special, unique and perceptive guy .... knows it.
I take nothing away from you when I say this Faris: you are 20 (oh to be young again) - what exactly does being alone for "a long time" entail for you? Months? Years? You'll find a few of us here on MM that can tell you that being alone for a long time for you might be a blink of the eye for others.
But to answer your questions (the best I can).
So you find you expect other things from a relationship these days? That's called maturing.
What you want today may well be different for you tomorrow. All part of growing older.
I know that all the hot, steamy sex in a relationship I looked forward to in my youth
no longer holds the same appeal for me today - oh hell, who am I kidding??!!
Yes it does!!!!!!!!!!!!!
All kidding aside, who knows - you may meet someone who will make getting flowers and little notes fun again. Or you may be forever past that stage.
