I'd like to add my two cents to this conversation - and it's really only two cents worth and probably nothing any of you haven't heard before.
Instead of looking for love why not let love look for you? Only a suggestions, but I found the love of my life by not looking - he found me!
Something you're passionate about? Find a forum on-line, or a discussion board that allows posts and add your input. Mine was divorce. After 13 years of a bad marriage that ended in divorce I went looking for a way to make new friends that were going through the same thing I was. Just opening up and being honest, asking questions, adding my experiences when asked without giving anything too identifying, those sorts of things, made me approachable.
What was so funny about the whole thing was there were just as many men as women that could relate to my experiences. Seems there's almost as many women out there that don't honor their marriage vows as there are men.
Once you have something in common with people it's easy to make friends. Friends stay in touch with each other, some more often than others, and more serious friendships develop with a few while the others move on. This type of forum is great for establishing friendships and e-mail can be the follow up once you're comfortable with someone. Start with a generic e-mail account, like Yahoo or HotMail, then when you're sure it's a correspondence you want to continue you can share your real e-mail if you want. The most important thing is to move VERY slow. Trust your gut..you'll know when it's a slime ball trying to move in by listening to your inner voice. Your new female friends from the same board can clue you in if they've been approached by someone too. When in doubt, don't! A polite thanks, but no thanks to an invitation to correspond by email should suffice. After all, you're still new to singlehood and aren't looking for anything right now. If he's a bad one he'll move on, if he's a good one he'll honor your request and will still communicate with you on the board.
Even if nothing comes of it, you've made new friends, probably learned a thing or two, and it's helped you heal.
