Hi Sarah, nothing would surprise me anymore with addicts – I’ve had money stolen, kids birthday money gone missing, he even spent his own sons birthday money on a bender with some homeless people when I was pregnant. I’m glad he’s your ex and my only advice would be don’t believe a word he says, literally nothing, block him on everything and never let him in your front door again, it’s nothing personal he probably does care for you but nothing can compete with the drugs unfortunately, hope you’re ok xx
