wtbh-
you're doing great. he is dangerous. illuminate the outside of your home. that is a very good deterrent. alert the neighbors. i agree with willy, nail that barn door shut. he is not reasonable.
is there a man you can have come and stay with you? your father? a brother? a mate?
this situation is escalating and he's out of control.
i was in a bar the other night and there was a very drunk guy. he was just out of jail the previous night. he said he went to his baby mamas home and she refused him to see their little boy. he was now in the bar, drinking heavily, saying he was going up to the house and breaking the door down. he didn't care if they arrested him. he thought it was his right. i said to him "go tomorrow, not tonight". he said no, he was going. i said "you'll get arrested and loose your rights to see your wee boy" he said he didn't care, no woman was going to keep him from his boy. i watched him stumble out the door, headed to hers. he could barely walk. that's the mindset.
stay safe.
