Somebody Help:

Ok dear, lets see

Well there's actually little or nothing you can do to prove it, until she's been with you and you don't dump her for a better target at the end of the day. Thats how you can prove it.

But till she accepts your proposal, just use your actions (that are greater than words) to tell her its she/her you love, do little sweet romantic things, surprises, just be a gentleman, and for the whole time when you're still wooing her heart, keep to her

At the end of the day (be it a moth, 2 weeks, a year), and you don't deviate from her, don't go after other women, be it for sex, long time relationships or any other thingy, she'll be damn sure its her and no one else you want and probably love, then you've passed the test of time and tempetation in flying colours

To her, you might fight tooth and nail just to prove you could get her, but if at the end of the day you still stick to her, then you're a graduate of love

The time taken, might feel frustrating, or too long but do remember that "no good thing comes easily", and at the end of it all, yo'll emerge the winner, because she's the perfect premier, thinking of tjose should make you hang on, don't give up, and give all you got.

Good luck, true love is hard to get, if she's your true love, then fight to have her no matter how hard
