Quickly because I had this love and hope so big but it was ruined just like that. Feel unappreciated.

love and hate are two sides of the same coin

No I don't think REAL LOVE turns into hate -ever!

Not quickly, but I've experienced feelings changing over time, as all things are subject to change. Love is a catch all word, but there are many shades, degrees and intensities of loving. It is a slippery fish to grasp onto

Yes. An ex gf went completely whacko crazy nuts on me. She apologized later, said she was confused about alot of things, but still. Was nuts.

YES. Very quickly. I build things up in my head and make myself think someone's right and it hurts more when I'm disappointed.

There are so many users and players in this world that I have to believe that the other person didn't really love to begin with.

Peeps are the ones who ruin it , selfish an have the big ego

I don't think it's ever happened that quickly but definitely dramatically.

quickly is a bit tooo fast
If its quick, did that said person even love them?

Not me, I give more chances. I believe in people then let go if Its a bad choice .

Not personally. I still have soft spots for people I was close to.

Never really hate.....
But, extreme disappointment, anger and hurt.

Yep, it's happened to me and it's not pretty.
