i met this girl in the internet a foreign women(Jessica) from US she is 21y/o, we've been chatting for about 1.5yr, and i fell for her and she said she love's me too, how the hell do i know if she really love me
Maybe she really loves you or maybe not, i wont give ya any hope but, like casually ask her to meet with you as you are in her city or something like that, if she agrees then maybe she loves you truly. if she tells you the whole activity of how her day went and all then trust me you my friend are damn special to her. if she tells you about her family, her dark secrets then she truly loves you.
You can pretty well get to know someone well over the internet without meeting first. if you are both speaking the truth to each other, but you do need to meet and get to know them personally. People often say this sort of love is just a crush, yet if you have been speaking to one another over a year now, you do have the advantage of taking that much time face to face getting to see each other, therefore when you meet, you will feel quite comfortable with each other. The thing about talking on line is that you will say things a lot faster than you would the other way around, give away your inner most secrets and if reciprocated it gives you an advantage, to enjoy the real yous when you finally meet. I say go for it, arrange to meet, take it slow don't presume you know each other inside out, let that happen in the normal way that it would had you met person to person in the first place. Good Luck.
