Welcome
What else are you doing to 'do you' other than trying to find a man? I agree that you should definitely get out there and find things to feed your own happiness and interests. Love seems one of the last things you'll find if you're actually looking for it. If you're miserable inside only you can change that. Depending on someone else for that is never a good idea. Maybe you've lost (or never found) your own identity being married for so long. I'd concentrate on that first. In my eyes online dating is a last resort. Just get out there and have some fun. Being happy isn't something you look for, it's something you decide you're just going to be. I'd say start by treating yourself... spa perhaps?? Meet other people and make new friends.. museum, a dance class?.. any social situation where you're exposed to people and new experiences can help you get out of that rut. Maybe therapy to push you towards realizing your own self worth. No one else can give you that.
