Tell me what you think I'm curious to know.

good question

if her eyes don't wander when you walk with her in public

when she wraps her lips tightly around you and you heard "gulp"

Well, you can always fall back on the IOIs (Indicators of Interest), do they lean in toward you, touch you, laugh at your stupid jokes, look at your lips, if holding hands and you give a little squeeze do they squeeze back. Or you could just ask them.

When she says, "I love you".

When she gets teary eyed during sex after an orgasm, plus she automatically takes items you dislike off your salad at a restaurant and puts on the items you do like from hers, even if she likes them too, plus she never says anything about the way you put the toilet paper roll on (including if you forget), plus she starts putting your favorite tunes on her iPod plus....

you get the idea, I hope.

I would say NEVER.My life exsperiances tell me that.The bigger your wallet,the bigger the words "I love you" in her asimil.Keep your wallet closed.You need a special glass to find these words.What i want to say is this.You will never know if she trully love you.You can married for a short period or a long one.There will always comes a day who can surprise you extremely.I know becouse i find out,more than one's.You can only take it like it is and cilently preprare to live with that treadment above your head.It can happened to everyone.

I would say when she tells you but those 3 words get thrown around so easily nowadays, even you men do it.
I can say as a female one of my body signals that I've found myself doing when I'm interested in a guy is looking into his eyes and fiddling with my hair. Sounds cutesy I know, but I've caught myself doing it without even realizing it. Just gotta learn to read body signals.

If she loves you, you'll know it. You won't even have to ask. Watch what she does, not what she says.

Oh, read it wrong. Forget what I wrote, and burn the evidence.
