I have been with my partner nearly 5 years now I have a 6 year old son from a previous relationship and me and my current partner have a 2 year old son together, my partner can be so loving at times and the best dad I could ever ask for for my sons, we have had a terrible past though he cheated stole of me and I forgave him he did change in that aspect but now there is a big problem come arise and it only happens when he sees he's doctor, he plays on mental illness to get special medications called zopicone and olanzapines he doesn't even really take the olanzapines which are for schizophrenia he tells the dr he hears voices etc when actually it's the medication making him mad, he abuses zopicone tablets which are a sleeping pill he will use a months worth (28) within 3 days, I asked him why and how dangerous this was he simply replies "too get a high throughout the day" he's more like a comatose zombie walking around he gets angry and shouts and me and our children and is very nasty to me with words, within the 3 days he's back to he's normal loving self until next month my 2 year old son is completely besotted with my partner, he promised me numerous times he will stop this but he doesn't stop and I don't think he ever will has anyone ever been with someone with an addiction before i am very scared of him at these times, my parents tell me I should leave him but I do love him and so do my children I am just fed up with him acting out every month thanks guys
