Please only helpful advice, I am way too hurt to have any crap in the comments. I don't have anywhere else to post this to so in it's the safest space I have.

I caught my other half doing speed yesterday and after a sit down I found out that he had done it a few times over the past month (& in hindsight I can absolutely recognise some of his newer behaviours and put them down to this)... Now he seems genuinely sorry and knows he has f-ed up. I hate drugs with every fiber of my being and I am so hurt, even more so because it was in our home whilst I'm heavily pregnant taking care of our first born, we literally had a chat a few days ago where he swore he wouldn't even know where to get any from and "hasn't touched them (drugs)". I really don't know what to do and really don't know how anyone can help but if you have any words that may help please make a comment.
