In-laws rant

Sorry if this is long, I just need to get it out of my system. I am 6 months pregnant, baby is coming middle of March. My husband is set to leave for the military beginning of January, he will be back just in time for baby to come. I have lived in the same area my whole life and I have always been very close with my mom, my in-laws live across the country. My husband and I were talking to his parents about how we just found this new apartment (that we are very excited about) and are moving in December 17th. His parents got really frustrated about that and told us that signing a new lease when he is about to leave would be the worst thing we could possibly do. He is leaving for 8 weeks, then we have no idea what is happening, but he will most likely be sent for training and I won’t be allowed to move with him until he finishes. So I realize we might not stay for the whole 12 month lease, but I’m planning on being there until at least june, and regardless the military will break our lease for free after he finishes training. Anyways they then went on to try to convince me to MOVE ACROSS THE COUNTRY AT 8 MONTHS PREGNANT AND LIVE WITH THEM until he finishes training...which means I’d live with them January-at least June. I wouldn’t have my own room, and my husband is the oldest of 9, so I’d be sharing a room with not only my new baby I’ll have, but his 4 and 6 year old sisters! Then when my husband finishes training I would probably have to move across the country AGAIN to be wherever they send us. I just think it is so ridiculous that they expect me to move away from my entire family, find a new doctor, have my baby there, and live in their already too full house with my new baby while my husband is gone. And it’s so hurtful that we called to tell them about these new apartments and they had such a sour reaction to the idea. We’ve been living in an apartment with a roommate since January and are so excited to BE ON OUR OWN for the first time since we got married, and I guess I was just hoping his parents would be happy for us too. I understand they want to be close to their first grand baby, but they have got to understand that what they are asking is wayyyyy too much. I don’t mind visiting, but moving there?! Why can’t they understand that we want our own space to bring our baby home to? We ended up arguing and trying to explain our side to them for almost 2 hours! They still keep saying that we just need to wait until my husband is about to ship out but by then it will be too late to move anywhere, or I will have to move all by myself at 7 months pregnant.
