Ok I am reposting the earlier message without the identifying details!
Bit of an update.
he replied:
"I know it was wrong. But I had stopped, and I backslid. I didn't, I wasn't, I'm not behaving like you seem to think."
And I replied:
*"I am not thinking you are behaving like anything.
I saw you behaving in a shitty way in front of a five year old with my own eyes. I saw you try to tell me my reaction was wrong - which it most definitely is not. You are now telling me you had illegal drugs delivered through the post to our home.
I don't need to try and dress this up as something. This is how you are ACTUALLY behaving, not how I think you are behaving.
Also please think about this - you had the stuff twice and you reacted differently each time. It made you totally wiped out... and you STILL think this is real cannabis? You are either completely deluding yourself or you are lying to me. You are getting some utter shite which could cause any kind of mental or physical reaction, that you cannot predict - that you have admitted you cannot predict - and I am supposed to be OK with you being in charge of our daughter?
I am not.
And I am not really ok with you messing around with your mental health and your body either, given that I'll have to pick up the fucking pieces if you end up in some kind of fucking psychosis.
I am absolutely telling you to choose. No ambiguity here. You get ANYTHING sent to our home again, I'm out. Smoke weed, fine, I don't like it much but if you must for fuck's sake get it from someone you know, and don't even think about smoking it round her ever again. You do, I am out.
If you can't promise me those things, then I am out right now, so think carefully about whether you can or not.
I am so upset. I am upset that you ruined what was a lovely weekend for me. I am upset that you tried to make out I was the one in the wrong. I am upset that you are such an idiot that you either think it's ok to get illegal drugs sent to our house OR that you still think it's ok to lie to me about buying synthetic cannabis, either one of these is pretty awful.
Believe me when I say this. If we break up because of this I will make sure everyone knows why. I will make sure everyone in your life, in my life, in her life, knows why. And I will make sure she knows why. Because you chose getting wasted over her and us. Everyone will know. I am not threatening you. I am promising you this is what will happen. You need to know how seriously I am taking this.
You have put us at risk and I am livid and I am heartbroken.
So it's your choice. If you choose to stay with us then there's no second chances."*
He has replied saying he promises me those things. And that he is terribly sorry.
I want to trust him because I love him so I will give him this chance... and we'll see what happens. I think I've been pretty clear on my feelings and as someone said upthread, this could be taken as an opportunity to address things and set boundaries. I don't want to break up our marriage and our family, I want to work together to sort it out.
I want to thank everyone, everyone on this thread who has taken the time to reply. Even those who said I was a shit parent! I genuinely don't think I am but it's made me think hard and made me realise that I wasn't overreacting. He's been a grade-A arsehole and he needs to show me he can do this.
I feel bloody awful. I've had to cancel my event this evening as I'm such a state. I'm so sad.
