I Am At My Wits End :(

hi everyone
my recently ex boyfriend has been on heroin for almost a year now and its been the worst experience of my life watching him go from the man i loved and admired to a full blown addict injecting h in the bathroom and falling asleep on the toilet lying to me about everything and even stealing from me and friends of ours
hes been to rehab twice for this and is still tttly unable to kick the habit its caused us to seperate. im an addict to to meth and im trying to get clean and help him get clean but its impossible.
im at my wits end. i dont know how to reach him anymore he thinks i dont love him and my going to rehab this week is a scary situation. i dont want to get a phone call saying that hes od :(
has anyone else had to deal with this? what actions did you take? please help ive looked everywhere for answers and so far ive got nothin.
thanks

Hi Raquelle, I am so sorry for what you are going through with your boyfriend. He really needs to get help himself. It's hard for you to help yourself and him at the same time, especially if he's not willing to get treatment. Please focus on yourself right now and on your treatment. Does he have family and/or friends who can help support him through this?
