My Ex and the father of my son, is/was an abusive alcoholic. We broke up a good while ago now, and I have been lucky enough to a) manage to get over the damage done to me in that relationship and b) meet someone who is respectful, kind and restores my faith in relationships. We've been together a decent while, I was really careful with him meeting DS and all has gone well on all fronts, it's coming up to the sort of time where we are considering him moving in with DS and I whilst we save for a deposit for a house for all of us. I know I need to tell ExDP but every conversation I have with him is so volatile and stressful I just don't know how to go about it. Do I just need to rip the plaster off and tell him? Or should I try and set up a time we can talk that's not handover? Should I tell him via text or email so he can react privately and then have space before he has to talk to us? I know I'm over thinking this but I have so many bad experiences of things I tell him "causing" him to go awol drinking for days, or being told that I tell him everything in the wrong way. Any advice?
