Hi eagle

your in your early 20s not married no kids!!

You have had the seat down talk, you have been romantic, she is willing to only hold hands and cuddle is playful but not interested,,,umm

Have you been really listening and watching her?? for clues!!!

Is there any chance as bad as this may sound there could be someone else??,,, Going away to a distant land and not knowing the language sounds good,,, great way to uncover where you are at,,have you told her how you feel and how the lack of libido iis making you feel??

just some thoughts ,,,I hope it works out for you.
