Janette132.. the sad sad truth is that drug addiction is so complicated, it becomes before everything. If i was 6 months in and found out about my BFs addiction i wouldve run a mile.
All i would say is, dont be naive, understand that youll never be able to force him to get help, he really needs to want it.
Addiction is a disease and it must be so hard for them to give up and stop – i can see that people tell you to leave him but with my experiences and the hell i have been put through first hand – my advice would be absolutely walk away now, you will have this for years to come.
Trust goes, you will live a life of anxiety and let downs.
good luck with it all whatever you decide to do, i hope he seeks help asap.
