Dear Sam, I have been dating a guy for about a year. When we first met he told me he had 3 kids by 2 baby mama's. Now that things have gotten serious, which he wasn't sure how serious we would be (we are talking marriage and moving in together) He has two more kids and two more baby mama's that live in another state. We are both in our 40's. Am I making a mistake with him?
