i know exactly how you feel my best friend got married a few months ago and it was so hard! she moved away and we hardly get to see eachother. there is really nothing i can tell you besides that seeing her so happy made it all worthwhile. my best fruiend made a point of introducing me to her chosson before they got engaged and told him how close we are and bh he is a great guy and he understands how we need eachother. we make a point of talking before shabbos and we text all the time just to say hi and we bith know that even tough we dont see eachother we are always thinking about the other. im not gona lie.. its hard but again… just kee p thinking how happy she is and it makes it so much easier!
good luck!!!
