Missing home is not a fun feeling and I am so sorry about this. I can relate to how hard this. Is there a way that you might be able to make some visits home in the interim, or get set up with a webcam with the friends and family at home to help, or to talk more with them before making any decisions, or even with helping to make any decisions?
Meanwhile talking with each other and listening is going to be the key. Perhaps there will be compromise such as a time limit on how long y'all will stay there, or his helping to pay for more visits home; or perhaps he or you are not willing to compromise and it is time to go separate ways. It helps to have a job lined up though if it comes to this or even if both decide to move for both of you. It still comes down to only you can decide what is in your best interest but you have to take care of you first and foremost. Life is too short to be miserable. There may be some other solutions though than to just move but if it turns out moving is the answer, do whatever is in your best interest and feel the most comfortable with doing. Hang in there meanwhile and with whatever you decide, wishing you the best!!!
