Being that girls tend to receive a lot of messages from men on online dating sites, there is always a really good chance that some of those messages will be from married men.
The married men who tend to contact girls on online dating sites will typically either blatantly lie about the fact that they are married on their online dating profiles or they may state that they are separated.
As a divorced mom with kids on dating sites, you should first be sure about what kind of person and relationship you are looking for.
When you have that established, you should proceed to join the right dating site for you.
Now, do understand that being that you are a divorced mom with kids, you will have to be realistic in terms of the kind of men that you are going to attract on dating sites.
