<human>: Can you succinctly summarize the text in 1-3 sentences?

It seems like it all started when she went on a work trip out of state for a week, then when she got back she seemed really distant.  I started to suspect that she had cheated but thats really not likely for her. Then about a week ago she broke down and started crying and said she was lonely.  We work different shifts and I work 50 hours a week usually so we haven't seen alot of each other. Anyways we talked about it and I told her I would do my best to get on her shift. Things went back to normal so I thought everything was ok then yesterday she tells me shes moving out and that her mind is made up. Once she left I was immediately devastated.  Now I just can't stop thinking about what I should've done different and if theres anything I can do now. I know if she doesn't feel the same for me I should let her go but we had a healthy 6 year relationship together it feels like I should try to save it.
<bot>: she says we've grown apart and we're not compatible.  I feel like we're giving up to easily. Idk what to do
