I mentioned it in my reply to @Adam Strange but have you and your mom considered the benefits of hardcore minimalist living? Assuming she's otherwise healthy and able to take care of herself (e.g. she can drive a car herself at least during the day and is able to walk around without too much aid) she can execute on getting a Vanabode for herself and likely be quite happy with that circumstance.
Hell, you can get one too and travel about as a pair taking care of each other without that damnable rent payment to worry about. Sell off the superfluous shit you "own" (protip: you don't actually own most of what you think you do or at least, you don't own the "big" items you think you do like, say, land or a house), cash in anything that you can that isn't Precious Metals (because the shit's about to hit the fan and lemme tell ya you'll want every ounce you can muster to barter with), acquire a PO box/negotiate a deal with a family member/close friend who has a street address/learn how "general delivery" works (if you're a US citizen who lives in the US) so you can still get snail mail and order shit off the net, and then tell your landlord the magic words every Gamma/Real American dreams of telling anyone who thought they had absolute control over them as you start up the van and drive off into the sunset with a mirth matched only by the most pure and innocent of children as they play with their favorite toy. Fuck You!
Hell, random thought, perhaps the ideal future will consist of extended families who went this route forming "caravans" and the like. Fun idea .
Getting more specific than this (and thus further customizing a solution to your given problems) requires me to ask you very personal questions that I won't ask in public. I've learned about tact (and how I tend to lack it) the hard way.
And then the last bit I always mention nowadays. If you have attachment issues (and you and your potential wife likely do), fix em'. If not for yourself, than for her. She wants/needs a man who is capable of truly bonding with and providing her with emotional intimacy. Women of all types crave that (hell, men do as well let's be honest). The worst examples of any type are that because they're broken to the point of being lost in that regard. Far as I can tell you aren't, I ain't, and most everyone here isn't as well.
Many are demonically obsessed, but the outright possessed and subjugated don't seem to be a major issue here. Yet another aside but a positive one regardless.
