One of the most traumatic things for children from divorced homes, is being used a pawns in the parents quest to outdo the other one. Rav Pam ZTL said that the Mizbaich cries at divorce.
There are many boys out there that need male companionship, to learn with, daven with, play ball with etc. When it can be their own father, Mah Tov Umanaim. But when it cannot be, Single men be aware that there is a great Chesed that you can do for these boys. Don’t always think that only women can do Chasadim. Sit next to one of them in Shul, show them the place, learn with them – act like a big brother not a substitute father figure.
( the same can be said for Yisomim) You can make a difference in the future lives of these boys.
