Tempted to go to DA’s house....

I would consider that a gross violation of privacy and wouldn’t open the door either.

mrob - He’d probably agree as would most avoidants, who by their nature, want to avoid.

On the other hand, my friend and her boyfriend broke up last year and after a few days of the bf not receiving her texts/calls she showed up announced and they had an adult talk w no drama. However, they are two secures. She’s one of the most secure people I know and she was still anxious by his ignoring her. And since he’s secure he wasn’t triggered by her presence. It all depends on who you are dealing with...

hannah99 - It may feel that way to you but in the US that’s not the law. A salesman, friend, ex or acquaintance could at any time show up at your door and it’s not harassment until you’ve told them to leave and they refuse. On the phone you must warn them three times not to call again until it’s harassment. You’re throwing around some serious words for a person showing up at your house that you don’t feel like talking to...

It's not about the law. It's about respecting someone's privacy.

Laws are important to consider, as are the avoidant traits are an avoidant. Particularly if your ex avoidant is avoiding you to the point that you are researching laws around your anxious contact.
In that case, it's prudent to step back, take no action, and talk to a therapist about your real issue, which is attachment to the point of obsession with a man who refuses contact.
This is an excruciating dilemma for you, for sure... but that right there is the meat in this sandwich. Your pain is actually the most important thing here, because it's about to prompt you to do something that is not in your best interests or his, even if your AP thinking has you convinced or nearly so, that it might work.

One talk without drama, should you be able to accomplish that in this highly charged situation, (UNLIKELY) changes NoTHING about this deeply ingrained pattern between you two. You don't need this one fantasy talk that gets you two on the right footing. This is an illusion.

This scenario is playing out badly already. You cannot predict what could happen , just like you did predict that your angry texting would lead to this point now.

STOP chasing him and chase your sanity. I am not insulting you at all. I have compassion for your agony. You will make it worse if you don't stop this emotionally charged pursuit that always goes One Place... to your abandonment.

You are repeating your abandonment pattern. Look at that. see it, own it, change it. This always ends with you hurting worse than before. You are pursuing a man who harms you with his retreat and this will not change except for the worse. I say that because your behavior escalates , his behavior escalates, you two are disastrous for one another.

I can tell you're very much engaged , like wrestling with this and with each of us. I understand it, you are in survival. This is an urge to repair but it's an illusion. When, any time that you felt this energy, did repair happen if you acted on it?

You need to calm that threat response with something that targets it on the physiological level. Anne has posted much about this. Actually try to land your nervous system into a secure relaxed non threatened place. That is your JOB as an adult here. It is your responsibility actually, if you know about it, to take care of your own body first and get control of this anxiety. It does not include him. This is all about you.
