I agree, go out and have fun. You are a role model for your children. Teach them that you can be a single parent (or even just an adult), who can have fun and enjoy life.
When you are happy and active, you will attract some one who wants to be with you because you are positive. Enjoy your time with your children to give them what they need (I don't mean gifts) love and good parenting. But most of all, enjoy your own company and find time for you to relax and reflect on what you can do to make yourself happy. Then do it.
Have fun
(I have reached the other side of this) I am now living again and my daughter knows that you can be single and happy with an exciting and active life. I don't have much cash, but I budget as much as I can, so my daughter and I can have a rich and varied life. These exeriences will lead to memories, that both us can cherish. My boyfriend finds my independants a little over bearing, but he also respects it.
