just want to know

hello,not sure where i was to post this at so sorry if wrong. need help,meet this beautiful girl online playing a mmo game,she is smart,witty,beautiful,and down right perfect in my eyes,i purchased her a airline ticket to come visit me in the near future.we talk nearly everynight and have exchanged pictures,she always tells me she loves me,but now she seems to be a little distant in our chat,i have the habit of sending her flowers on a regular basis,last night she told me to stop sending her stuff,because she was unable to do the same.how am i supposed to take that?i dont expect anything in return from her.how do i check to see if she is on a dating site or sites to see if she is trying to find someone closer.i just want to know now instead of later,dont want to go thru what my x wife put me thru,she basically made it hard for me to trust.can someone give me ideas,im going crazy here.thank you
