M27 f33. me and my girlfriend were engaged but she said she lost feelings?

So my now ex is temporarily in California donating her stem cells and her kidney to her 6yesr old son and she’s been there for months stuck in a hospital etc and won’t be back for months she says she’s very depressed and stuff and said she’s lost feelings for me. And I haven’t given her time to miss me and stuff. Should I trust her to come back around or is it done done?
