I'm sorry in advance if this upsets anyone and it is a long post so thanks for reading but I'm just looking for some advice. 
​We'd been living in Cyprus and decided to move back to the UK. We came back in July. My son was living with my parents in Cyprus until we found a home, work, school etc but I struggled being away from him. My parents weren't planning on coming to the UK until this month (next week) so for me it was too long. I hit a depression and needed to be with him. At the same time oh went back to his old ways being in his home town and around his old friends put him back to a stupid 17 year old. 
​Long story short he started treating me differently going out with his friends and leaving me at home worried sick about where he was and what he was doing. He'd always come home and apologise and we'd be fine again til the next time. It got too much and I left in September and went back to my parents and son in Cyprus. He told me he regretted what he'd been doing. It was just alcohol and him spending time with his friends which normally I wouldn't have a problem with but I don't know anyone around here and felt left out. 
​I wanted to give him a fright and felt like it had worked. 
​He swore it would be different and he knew I was missing my son and he felt helpless. He was crying on the phone everyday and wasn't taking care of himself. After complaining about wanting to see his friends so much he didn't leave the house. I believed him and believed we could work it out.
​After 3 weeks I took my son and came back to the UK. Resulting in a fall out between me and my parents.
​It has been so different he's not been going out and hasn't been drinking. Then yesterday he went for a haircut and came back 3 hours later with a bottle of methadone. 
​He then told me that while I was away he'd taken heroin on two occasions with one of his old friends and that he has an opiate addiction. 
​All I knew in the past 3 years is that he has anxiety and I thought the pills he'd been taking were Xanax. He did stop them for a while but replaced them with steriods and they changed his personality. He seen a doctor and was prescribed Xanax and when they ran out I thought he was going cold-turkey.  Instead he'd got his hands on subutex and told me he was cutting them and taking a smaller dose each day to wean himself off. I didn't know at the time they were subutex he'd given me a different name incase I looked it up but he came clean yesterday and told me everything.
​If I had known he was doing this I would have stayed in Cyprus but since I left with my son against my parents advice were no longer on speaking terms and have told me I've never to call or speak to them again. They are really angry with me and while they're here they've asked my brother to babysit my son one night so they can see him. I've not to be anywhere near them and they've made it very clear. 
​My advice to myself would be to leave his sorry ass but it is actually impossible. I have nowhere to go and put the money I had into this house. 
​I know he hasn't been doing any other kinds of drugs and absolutely none around my son. Even the pills steriods and Xanax he's kept well enough away from him. 
​What I need help with is understanding this stuff. 
​I know he wants to get rid of the addiction but how long will it take? 
​Weve been ttc since April but I'm sorry to say I'm actually relieved af came early because I don't know how I'd feel if I was pregnant right now.  
​Will he become addicted to the methedone? 
​What should I expect? 
​Any advice would be great but please don't say leave him because at the minute it's not an option or I'd be long gone.
