I can relate to this a lot. I am currently 13 weeks pregnant, I actually didn’t feel ready but he convinced me that it would be the turning point to change his life around. From when he knew up until now, he’s been using cocaine and then drinks after as well. Goes on binges and missing for days at a time. Whenever he’s exhausted from taking it he comes back home and says that he’s done and he’s gonna stop. He didn’t bother to attend any appointments for the service I referred him to. He’s recently got worse, started getting in trouble with the police for being intoxicated and driving his car. He started harassing me and made threats to damage property. He was told to not contact me as part of bail conditions however being so desperate for money to take more drugs he ended up breaking the conditions and showed up harassing me again. Your partner just like mine is stuck in an addiction cycle and will only recover when he breaks the pattern. I notice that after using he feels guilty and apologies but it’s only a matter of days before the irritation starts and the craving kicks in and he’s back to sneaking off again.
