Ohh i see, his mom just felt guilty and seems losing his child makes her feels miserable too. Maybe when she see him it always remind her of his guilt. But thats not a free pass for u to neglect ur own son tho. I feel sad for the black hair guy but seeing him being optimistic to not getting attached to his mother again is good. Some things/conversation are better left unattended because the past is the past. As long as it will keep u moving on u re good to go without it.
