What a great opportunity to talk to the person with whom a talk will make an impact: your son!!
I'll say it again - I was your son, except it was my dad who was the A, and I can tell you unequivocally it would have made a world of difference to me if my MOM had the courage to talk to me about what was really going on! I was so scared and confused, and it was such a TABOO topic between us.
Yet it was REALLY happening and affecting my life & my thoughts. Day in and day out. Why couldn't it have been an ongoing and healthy conversation??? Why not??? It was an ongoing problem. Because we need to pretend it isn't real? Who does that actually benefit?? No one benefits!!!!
Peace
