<human>: Been living with her for about 2 years. High school sweethearts, first major relationship for both of us. Had our share of issues. She felt like we were incompatible sexually (which admittedly we struggled with) but also she felt like she had lost part of herself in our relationship. We  had a brief split a few months back which fell right back into old habits and the problems were never fixed. Overall she was no longer happy. She said I treated her well and she still loves me but that it felt like we were best friends rather than a lot term committed relationship. The one that hurt most was "I wish I could meet you two years from now" because we were in different stages of life. 

I built a life with this girl, as much of one as two so young could. We were looking for a new apartment. I just got a new job. I just put my dog down and I won't see our cat since she is most likely keeping her. I lost my friends a long time ago. I'm moving back in with my parents. I've never felt so lost, and so much loss at once. My beloved and best friend, two different pets, my home, our friend group, her family, just everything. I feel so empty and lost and I don't have anyone or anything. 

Probably very dramatic but I'm devastated. I formed such large parts of myself with this girl. I have nothing. I definitely lost part of myself in the relationship too but goddammit at least I had her. At least for a minute we had a chance. Fuck.

Could you distill the essence of the text into 1-3 sentences?
<bot>: Built what was for me, a life with this girl. Both of us lost part of ourselves in the relationship, I'm very alone now and absolutely devastated. Lost everything I cared about. Hurting and alone.
