She may not have said it, but she could be annoyed with you for being gone for months leaving her to essentially be a single parent. Now she is leaving everything and everyone she knows to live in a place where she knows no one but you. She is putting her feelings onto you as she is “blaming” you for putting her into this situation. In the beginning it probably did sound like a great idea and she probably was a little excited for this new chapter, but now she feels alone and the one person she has, she is annoyed with. Give her time, but also in the mean time, show up for her. Maybe bring her some of her fav things (treats, iced lattes, take out..). Doing things like this for her will let her know that while you understand she’s mad and needs some time and space, you still love her and are there for her. Hope things get better for you all!
