Trust me, having no friends is better than this. I found some friends at a stuttering self-help group. Does your town also have one ? This might be a good place to start ! If you want to make an effort to rekindle the friendship with them, you will have to talk about this issue in a serious manner. No bullshit. If they don’t respect your boundaries than the friendship is over. If you lay out your feelings honestly, then true friends will respect that.
