Yup.

The pattern - falling in love, falling out of love, finding a new love,
falling out of that one, and then finding another, ad infinitum - is very
typical of depression. It's driven by the absolutely conviction that if you
change partners, change jobs, change locale, change your life . . . well, then
you can leave the troubled present behind and start anew. The realization that
all of this is caused by the depression comes later, if at all.
