Well, one advantage of starting out again at 40 (or more, in some cases!) is that you know a lot more this time around! So you can make new mistakes, instead of the same ones you made the first time!
Hopefully when you do find the person you are looking for (and I haven't totally given up on your idiot...I mean, H) your kids will get to see a better example of what a M should be. Hey, I'm looking hard for silver linings!
I'm sure you will be loved again, you have always sounded like a wonderful person, from the first evening we "met"! Who knows about marriage, never say never!
