I think you should just make the plunge, she may be forced to grow and mature more herself then, just my opinion though

I mean, I am sure if you ever want a normal relationship with a women, you already know the worst thing you can prbably say is that you live with your mom, no matter what the reason, unless she was in her last days ofcourse.

I never really had a very close relationship with my own mother, so
it is kinda hard for me to put myself in your shoes, though since she
has no retierment, I have planned to provide a house for her in her
old age within walking distance, but not under the same roof

I hope you can move on with your life soon
