No, don't give up on meeting someone, but always make sure your kids come first. I don't know how old they or you are, but I imagine it would be a little bit easier if they are older, they would need less attention and you would have some more free time for stuff you like. I wouldnt want to date someone my age with kids (they would most likely be less than 10), but maybe if I were in my late 40's it would be a different story
