I have two children both toddlers and a sibling who is an ex heroin addict now on a methadone program. My family all disowned my sibling 4 years ago but now everyone is playing happy families again except me. The problem is my sibling is/was a compulsive liar, has had so many chances to change I've lost count, hasn't seen their own child for years, has stolen from my parents and other siblings. I haven't spoken to them for four year after my parents disowned them. I have shielded my children from any sort of violence/ drug abuse because my mum was in a violent relationship when I was a child and some of my first memories are of violence. I want to keep my children innocent and pure for as long as possible but my family think I'm being unreasonable as apparently my sibling has now 'proven' themselves by staying clean for a whole 3 month. I do admit to feeling guilty about this but probably because of the pressure they are putting on me. I don't want my children to meet them and get attatched then lose that person because they've relapsed. I'm so confused about what to do for the best I don't know if they are clean or not I only know what my family are telling me.
