WIBTA For Evicting my Parents?

I'm posting this for my cousin who is afraid of the ramifications of evicting her parents and doesn't quite know how to ask the question on reddit herself. She will be reading all of the comments and approves of this post. The following will be written from her own perspective. 

My parents are living in my house. They were evicted from their own apartment due to inability to pay rent and to make things easier, I (36F) and my daughter (11) moved in with my boyfriend (35M) of 4 years (now 5), and let my parents move into my house. 

My boyfriend, lets call him Jeremy for the purpose of this story, agreed to let us move in and stated that I wouldn't need to pay my half of the rent to him until my parents (both mid 50s) got back on their feet and were covering the mortgage. It has now been 15 months. I have not received a single payment from them since late 2023. 

This is obviously straining my relationship with my boyfriend. My brother is helping with what he can, but he is out of state with a new wife and baby of his own, means that he can only do so much, but the help of these two amazing men, has been all that has gotten me through this.

The stress of having to cover the mortgage for my parents, with the stress of feeling as though I'm not pulling my weight in my own home, leaves me with wondering what I can do. I have provided them with multiple resources to get on disability or other government aid, but they have not pursued these options. 

I'm faced with having to cover the mortgage for them indefinitely, and stretching myself very thin with zero savings or ability to put away for the college fund of my daughter. The house flooded in 2019 and I had to take out a loan, max out my credit card and use all of my savings which were supposed to go to her college just to repair the house. Her college is entirely wrapped up in this house. 

I decided to tell them that I wanted to sell the house. That was a whole year ago, in February 2024. They have not been able to move for a myriad of reasons. And after a tumultuous year of strained relationships, they won't really communicate with me or answer my calls. They only answer my texts. 

I don't know what to do at this point, but a decision has to be made.

WIBTA if I pursue legal action and evict my parents?
