Idk what to do

So explain to me how tf this works I'm not abusive at all emotional and explosive when it boils over sure so my partner wants me to move out and back into the travel trailer I have I personally don't want to its full of mold and busted *** from us living in it homeless id rather sleep in my car she says she still loves me but can't live with me anymore why keep me yet boot me out the door this is the kind of *** I can't fathom she moved in with me initially to get away from her mother soon as we moved too where her other partner was she grew more distant no bedroom action no close cuddles it's always either some kind of *** or having me do the whole house or try to anyway FML I might as well just find a cliff or bridge since she obviously don't need me anymore especially money wise went from working and helping her with bills to now I'm more broken both body spirit and wallet guess I'm not meant to have anyone this is the longest relationship I've had and now as usual it's going sour right in front of me and I feel like I can't do ***

We are trying to work thru this but now it's you can't spend the night can't be over for more than a few hours for preface we are polyamorous she has a gf/wifey that I consider a friend but our one rule is we tell each other everything about having another partner open trust and the way she says things about me not spending the night and only a few hours during the day makes me think she has someone else on the line that she's gonna replace me with
