Hey there. Firstly hope you’re okay. It’s such a shock to the system when you first discover or realise they have an addiction. What i will say is while they are in a active addiction anything they say or do will not make any sense to a non user like yourself. They lie and become manipulative all to keep the addiction going, it’s part of the brain or the addicted brain as they say that’s affected that does this. Deep down the person is still in there but the drugs cloud their judgment and good decisions go out the window! It seems to me he has a serious addiction if he’s nose is now damaged due to he’s use. I personally would say to leave an not look back unless he’s clean for a long period of time or changes but that’s up to
him you can’t control or change it he has to want it. If i didn’t have children with my partner I would of not looked back and left the whole situation. It’s no life and it will always be a worry if this is something your prepared to do then it takes strength patience and sanity. Take some time for yourself try take your mind of it I know it’s hard but it will help you. He may be keeping away because he’s ashamed and knows he’s hurt you they do feel but they won’t share or act like they care it’s a typical addict trait. Take care x
