Could be due to anything & some find this time of year especially difficult.Wonder if something has happened already? I know he's still following her but her stories are very intense this morning. They can't have got that serious that quick for her to be like this. She'll have to get used to him being away from time to time if it's serious. Wonder if she falls hard and fast.
Good that she is talking about it & being open.
I think she gets very invested in her relationships. Maybe she will talk about it in the podcast
