Hello Jen, welcome onboard
It's good to know that you like the M2 family already

Now, coming to your topic - most of us, who are about our age, are parents, and single too! But not necessarily, lonely! True, once the kids grow up, they have a life of their own, and the single parent begins feeling lonely! It seems, only till yesterday, the kids would take so much of our time, and almost overnight they have grown up; no longer asking for our undivided attention!
This is one stage of our lives, most of us are never really prepared for! This is where sites like this one can ease out things for us, by at the least, not letting us feel that lonely! I wish you all the best, happy mingling....
