Need Reassurance

My mother lives with my sister. My sister has seven kids and has become an intense fundamentalist in the last few years. My mother hates it and now does not like living there.

My sister's husband is a week, but my mom lives there for free. She's an alcoholic and they don't love it so she feels like she has to "hide it."

She has been calling me the last few months gossiping about my sister and how she "has to get out of there" but keeps saying "she has to figure it out" and then saying she will have to just "ease the load" by staying with others sometimes

She works in my town but lives an hour away. She never wants to drive if it's raining and has asked me to commit in the past to letting her stay here "when the weather is bad."

This concerns me greatly. Last time she was here was a month ago and I was so triggered I spiraled. I don't get why she doesent get a job closer to home or find a place to live closer. She always says she has no options. Anything I suggest she says I DONT WANT TO DO THAT. I feel like she is thinking she can live here and is wanting to ask. My husband and I moved out 13 years ago and she went to live with my aunt for free. She didn't save a cent, spent it all on wine and then they fell out and she left. Went to another lady. Hated it. She went to live with another aunt who nailed her out for free. Two years go by, doesent save a cent. Falls out with them. Moves out one day when they aren't home. In with a friend. Same situation there. Now she's at my sisters.

I feel so guilty but I also know in the truest way in my soul it woukd destroy my life. My husband's life. My marriage. All my sanity. My finances.

But so many people tell me she's my mom, how can I abandon her, I have the space, it's close to her work, blah blah. I don't see why any of that is my problem. She has had 13 years since I moved out to figure out her next move and she always expects people to jump in and bail her out because they do.
