I’m very sorry to hear about your boyfriend. Single-parenting is a tough road to travel, but if he is actively drinking, you would have ended up doing all the parenting yourself anyway, even if your son’s father was physically present. There are plenty of members here who are effectively single moms/dads even if the other parent is still around. I hope your son can have some relationship with his father, despite the limitations imposed by his addiction. You're going to be okay.
