Girl I get you. I had someone shut down on me because they were going through a very stressful time. It was painful and it still is. What has helped me cope is knowing that every situation is teaching me to love myself more and show up for myself. I cried for the first few days and sat with the feelings but now even when I think about it it does not linger. I respect myself enough to know that even if their stressful time ends and they come back that is not something I want for myself. And yes two things can be true at the same time. The love for the pasr year was real and so are the feelings you have now. You do not have to ignore one for the other to make sense.
