First, congratulations on taking a big step out into the dating world. The great thing is that you don't have to let anyone meet your baby until you are 100% ready for them to meet her.
By waiting to introduce baby to a boyfriend, it protects baby and saves you the heartache.
Think of the kid of man you would like and go from there. I am guessing you would like one that is responsible, kind and marriage minded. If that is the case, than try talking to some of your older friends or your mom and her friends and see if they know of anyone worthy of dating you. Sometimes when we want something so bad we put blinders on and don't see what we are getting into. Your mom and her friends are going to have your best interest at heart.
Set up a few rules for yourself. Like: they have to have a job.
Hope this helps. Keep us posted!
