There are other areas where he gets the chance to try again. So my boundary here is about what I can handle, which in this case is that I cannot and I’ll be done. I mean that’s what boundaries are after all, I cannot control him, but he can be aware of what I will do to keep myself safe if he chooses to mess up. He can decide if the consequence is worth it.
I just think it’s not fair to expect every SO to be understanding, to be ok with what a relapse means in this addiction. If this were alcohol I’d be much more understanding. And I know it is an addiction. I know there are brain chemicals involved that are very difficult to overcome. But there is an extra damaging element to relapsing here that some women like myself cannot do. Thankfully my husband was already in a more stable place and could see that I just can’t take it if it happens again. He removed all areas where he could have come across anything that might initiate a slip or relapse. Most of them are still permanently gone because it’s just not worth it to him (e.g. social media, other media over a certain rating, etc).
