You should not attempt to find your mom a boyfriend.

The world isn't the way you would like it to be.
She wants a guy that could have most any woman.
And her desire, what she will accept does not go down as she ages.
So, the pool that she can find that matches what she wants are all bad-boys.

You will just end up wasting your time, and the time of whomever you try to encourage you mom to meet.
