My girlfriend is looking for a house, this has caused her stress, has demotivated her, and is distancing herself, what do I do?

she loves her family a lot and is tired of being so far from them, so she decided to move closer to them, but she has been stressing for the past two weeks, and with each day she grows more distant. tonight she removed her profile picture and said she will talk to me the next day. our relationship is in a good spot, but ever since she started looking for a house, she has been very this way and has been getting worse. I’m worried for her and feel I should give her a day or two for space, but I’m not sure if that is smart either
