Anyone ever worry about spouse after divorce?

I’ve (47m) been thinking about divorce for a while now but part is just scared of blowing up our life and I honestly worry about my wife’s (52f) life afterwards. I think we both have potential to find happiness but I know I have better options. Like I could stay with my mom for a little while until I figure things out and I’ve always been the bread winner so I will maintain my job/career. She was a full time SAHM forever and has only been back to work part time for 4 years. She doesn’t really have viable option for place to stay if we sell the house and she has anxiety to where she can’t drive any significant distance so I’m assuming if she moves to an apartment somewhere it’ll have to come with a whole new job. I know there will be alimony to help her out but she’s still the mother of my daughter (19f) and I want her to be okay. I don’t hate her at all, I think we’ve just grown out of love and now that our daughter is out of the house it’s all just become readily apparent.

I’m so torn with what to do. Asking for a divorce will blow up EVERYTHING. I think my daughter will understand eventually but would probably hate me for a while too.
