Does being a single parent mean that your love life is over?

The reason Im asking this is because I was having a chat with some friends the other day about a date that I went on ( complete flop but made a new friend ) and they said that my problem is that I have 4 kids and no man would want the responsibility and basically I will be single until the kids have grown up. 3 of my kids are 9 and over and the other is 5 so does that mean Ill be single until they all leave home? Im average looking. With a fab soh and can hold a conversation but always seem to end up with new friends when I go on dates. So, what do you think? Is someones love life over just because they have kids?
