overstepping yourself by planning to build adjoining homes for you and your mom and/or assuming she'll never want to date and marry again.

I don't necessarily think she'll never want to date/marry again, but she certainly thinks that. Adjoining homes was her idea, not mine. Not really even adjoining, I'm looking at a 9 acre plot right now. That's plenty of space.

If you're really concerned for their well being why isolate them on a plot of land with just you? Why not help set her up find an area with a community of good people her age easily available? Why not find a neighborhood for your brother to grow up with kids his age where he can walk to his friend's homes?

You aren't considering the fact that none of us want to live in an urban area. We like it quiet and rural.

In fact, there are a lot of things being said in this thread that don't take into consideration that there is far more going on in my life than just what's written here. There are a million factors at play for everything mentioned. I don't know why people are assuming that I'm deciding things for my mother and whatever else is being assumed here.
