I'm not a mum but I will tell you what to avoid. Many single mothers convince themselves that no great man will want them now as the have kids so they settle for someone who doesn't treat them as well as they would like. Do not make this mistake. You are worth a great man who lives up to all your standards and expectations so don't settle for the wrong guy
Also dont introduce any man to your children until you are sure he is 100% committed to you and take things slowly
Good luck
