As you said Up, noone knows what the future holds. As long as you are happy it matters not whether you are with your husband, with someone else or by yourself. You have your kids, your family and your friends and if I've learned anything from my wife in this journey it's that you'll be just fine without a man as you will be with one because of your support network and what you've learned. Good luck
