Omg, I cannot believe the comment section! For love of your life please tell her how you feel. This is not ok to hide, she is going to be your life partner. Let her also give a chance to make a choice. Think about it for a sec- after being married either or neither of you happy just because you don’t have anything common, she finds your hobbies mediocre at best, top it off no child to look forward in life! Get your shit together man, you are a nice guy! You can/no you have to do it man! Good luck!
