I understand what you are going through, sister. Perhaps that feeling you are describing is more attributable to 'isolation' than homeless. Humans are herd animals... especially the females. We don't tend to function well in isolation.
I am also 'stuck' in a rural town until my boys graduate from high school. And even though I do a good deal of traveling, I am around people (given their hockey functions, etc.) I still feel isolated. I mean, really, one of the loneliest places to be is in a crowd.
What I continue to hear you say... is that you are lacking intimate connection, physical OR emotional. There are times when the physical connection can superficially satisfy you for a time... but eventually, as with GB (GP? GG? GH?)... your xBF... when you understand that there is no point being with the person other than having a pointless, meaningless yet sexual and perhaps even periodically mentally stimulating encounter or string of encounters (dating for the heck of it), you are left feeling even more unfilled and more isolated than if you had not started the 'dating for the heck of it' experience to begin with...
So your bunny and your monkey get 'hurt' by insincerity and complete lack of genuine trust, your cow's milk supply becomes iffy because there is no farmer in sight, and your lioness... well... she becomes somewhat depressed, for there is seemingly no purpose to her hunting or protecting...
