Moving in with the in laws

So my fiance is going to basic in April and to try to save money for us to get a house after he gets his pds (permanent duty station) we were going to stay with his parents and I was going to go work with his mom at a store she manages. Well we would be moving in this Thursday coming up and I'm so nervous. I have a good relationship with his family I just feel like it's going to be a little odd living with them. They still have rules that I can comply with, but I don't know how it's going to be after my fiance leaves and it's just me without him. I guess it's just a new experience I'm going to have. So nervous I hope nothing becomes weird. Has any of you ladies lived with your SO family??
