L.B.
My son is 16 and has yet to meet one of my prior boyfriends. Oh, he knows that I date, and asks about them, but I have always told him when I am ready to marry him, then you can meet him. So far no marriage material. Tho' the current guy - my son may actually get to meet this one.
Being a single mother since conception I knew I didn't want my son to meet and become attached to someone that I may not stay with. He deserved ( and continues to deserve) all the stability that I could/can offer him.
Years ago, a little boy in our neighborhood, told us about his 3rd Daddy. Seems his Mommy often moved the boyfriends in - he was about 8 maybe. Broke my heart. Broke his heart when they left.
