Good work. I've had to go no contact with several of my old friends because their behavior was toxic, addictive, or otherwise yucky, and then in a weird twist of fate I had two friends from my distant past look me up this year and demand my attention. I also remained no contact with them, except in the case of the one that is a known alcoholic, who I told I hoped was well and sober, but that I have no interest in speaking to him and not to contact me again.
I don't have any regrets about it at all, and in fact I'm more at ease and have a lot less anxiety in my social life.
You can do this however you want. Do what makes you feel at peace with yourself.
