In an effort to resuscitate an already dysfunctional relationship, women will frequently make the fatal error of bluffing. Your girlfriend will repeatedly threaten to break up with you in order to scare you into changing (for the record I wholeheartedly disagree with this method, but that discussion is for another article), hoping you will prove your love by doing anything to make her happy. It never works, and you rarely take her threats seriously. So you break up.
Swetnick has told NBC News that she saw Kavanaugh "paw on girls" and "[touch] them in private parts" at parties as a high school student, but stopped short of claiming that he drugged or sexually assaulted her or other women. MSNBC aired an interview with Swetnick on "The Beat with Ari Melber" Monday evening, with reporter Kate Snow noting that NBC News "has not been able to independently verify [Swetnick's] claims."
In your case, keep NC shorter than 30 days - usually, around 2 weeks would be enough. Reach out but perhaps you might want to consider all the angles first before deciding whether to tell him or not about your addiction. Some people might take it the wrong way and instead of even feeling pity, it pushes them further away because technically, you weren't being honest throughout the relationship. It might be better to come across and tell him that you've changed and leave it at that unless you know for certain that he would be understanding towards your situation.
You have spent a month not contacting your ex. You spent that entire time working on yourself becoming more and more confident as the days past. Everything seemed to be going fine until you hit your first road block with a negative response. Make no mistake about it, negative responses are never good. However, they don’t EVER mean that you should give up right away. It just means you have to be smarter about how you approach things. Lets take a look at a negative response example (from my past) this is a true story.
You'll have to try and figure out what it was that made him break up so suddenly with you before you can determine the steps to take. For the time being, focus on self-recovery and pick yourself up from the breakup and perhaps even come to terms with it. If not, you won't be able to take the proper steps in trying to win him back. You can apply no contact for now, and when you've recovered, to attempt in re-connecting with him. Hopefully by that stage he would have unblocked you and be more receptive towards you.
