My live in partner’s personality slowly (imperceptibly) changed until he was unrecognisable from the man I first met. Our relationship went to absolute shit and he very nearly lost his job due to frequent absenteeism. Following months of increasing hostility and arguments, I finally told him it was over between us. I meant it that time and he sensed it. The next morning he sat on our bed and he cried. Fessed up to a chronic cocaine addiction. Told me he’d been using daily, every 45 mins for the best part of 2 years. I HAD NO IDEA. One week and many, many tears later, I dropped him off at rehab where he’s been ever since (1 month sober today!). It’s very early days and at times it’s been a living hell but I’m hopeful that both of us - whether we stay together or go our separate ways - are moving towards a happier, more peaceful future.
