Welcome to PsychCentral, Reasonable2012. I'm sorry you're dealing with a bipolar fiancée & feel that you are faced with such horrendous choices! I agree with Rohag ... giving your dogs and home away can't be the best solution, or even a practically good one.

If give away your home, where will you and fiancée live? How would you monitor/insure continued good care of dogs & property? Issues snowball.

Is your fiancée being treated? If so, is her therapist aware of your situation & plans? How about her family, and your family?

Please contact social services both public and private in your area. And stay in touch here. Lots on wisdom and experience on the boards. Take care.

Roadie
