J.,
I can only imagine what a difficult choice that was for your children to make. I too chose to live with my dad after my parent's divorce. But I still spent, and now do spend, plenty of time with my mother. While my mother still had my sister at home I did see that her immediate response was not to go seeking to fill free time with a male companion. And trust me, she had people who wanted to woo her! As a Christian you know that is ultimately God's decision to bring someone into your life - or not. My mother became very active in my sister and I's after school activities. I was in college cheering when living with my dad and she came to EVERY game!! She met my friends, their parents, and got involved however possible. Some other things you could consider could be group exercise class or a quilting club or even a cooking club or volunteering at a nursing home or continuing education classes or computer design classes, scrapbooking clubs and bible studies or home teams?? The list is so bountiful, I am sure there is an outlet for you to meet great people and not just fill your time, but enrich your life. I'll pray God leads you to the next phase in your life exactly how he intends.
