I'm currently sat outside DF's (73) house having a panic attack. We've never had the best relationship and we didn't speak for a decade but reconnected before Covid. I was pushed into this decision and massively regret it.
DF is manipulative, nasty and just generally made my life a living hell as a child. When we first reconnected he managed to be civil but over the years has gone back to his old self.
DF has lots of family that do not speak to him because of his behaviour, and he is feeling isolated and is constantly reaching out to me. The problem is he overreacts every time I do not answer the phone (I'm at work), by sending a barrage of texts saying he is worried and is going to call the police. This forces me into contacting him. He also constantly gaslights me by telling me I've agreed to do things for him when I haven't, and plays the 'If you loved me you'd do X card'.
I cannot cope with this anymore, I have almost been physically ill from the thought of knocking on his door (I agreed to come around after putting him off for 4 weeks) and I just cannot do this anymore.
My issue is, if I go NC, he will be on his own. He won't have anyone and I feel guilty for this, but it's also not my fault he's pushed everyone else away. AIBU? Do I just suck it up? Any advice from anyone who've been in a similar situation would be appreciated!
