Thanks so much guys for all the feedback.
I do agree the best decision probably would be to give the friend a second chance and see if his behaviour does change. What makes this hard is that its been 3 months since I had to cut him off and I've been really happy moving on with life and just want to get on with things now without any drama. Losing him for good isnt a bad thing tbh the friendship we had before did feel very forced but at the same time the best thing I can possibly do for the benefit of the group Im in his to make ammends with this person but not be close friends in any way.
Again thank you all for your help
