Rant. I just want my husband back

I'm honestly sick && tired of this poly relationship that I started with my husband. I don't want this woman in my life. I tried so hard to get him to change his mind but now she's living with us. He pays so much more attention to her. It's like she's some new toy...

I feel so alone. I feel like I'm not even allowed to be jealous. He says I'm not allowing him to have feelings for her.

I'm getting to the point I'm gonna say fuck it && leave...

I just want my husband back. That's legit all...
