Middlepath, maybe this is a test. Maybe Hashem wants to see you stand up for yourself and has done his part and is waiting for you to do yours. Maybe it is time you were nice to yourself for a change. Why NOT say how you feel? Why not say “I understand that you need time and space to think this through but while you are taking that time and space, please hear me out and give some thought to what I am saying and what I am feeling”. Then tell her “when I met you I couldn’t understand why someone like you would want to date someone like me. We are from such different backgrounds. I didn’t even know if I deserved someone like you. But then my friends made me realize that Hashem is in charge of shidduchim and if he put us together he must have a very high opinion of me and obviously feels that i deserve better than what life has handed me till now. I began to realize that I am deserving and I am entitled to have a wonderful wife and a wonderful life. I am entitled to have an amazing and successful future and I believe I can have that with you. It hurts me and saddens me that we are not on the same page. I can’t make you feel about me like I feel about you, but I hope you can give me a chance.”
MP, that is the best you can do. If you don’t speak up for yourself then you will allow every good opportunity to pass you by. You can’t force things to happen but you can give it your best shot.
