Heroine Addiction

My boyfriend and I have been together for a year and a half. Towards the very beginning of our relationship he confessed he was using heroine. Ten days ago he decided to go into rehab, now that a week has passed he is able to make phone calls etc... He's even Ablett call me. I called and called and even texted him like 15 times until finally he texted back saying he needed to focus on himself and didn't know how he felt. We love each other very much and been through so much together. He once told me he needed me to help him become sober.
I just want to know if I should take what he said personal or does that mean I should move on?
What's your.guys opinions, please help me I'd appreciate it so much!
Its nothing personal...trust me.
He is in his own personal hell right now. He is learning how to deal with this. He is foggy headed and probably doesn't want to talk to anyone.
He needs you to be patient. He needs to focus on himself right now.
It has nothing to do with you.
I would expect him to be distant like this for about a month. The 6 months following that he may feel very depressed and week. (I did).
Quitting heroin is a big deal. He will go through stuff that you wont and cant understand.
Just be supportive. Don't expect him to be able to fulfill your needs for a while. He has enough on his plate.
Him getting clean is the most important thing above anything else...even you. And when he gets over the hard part he will be so thankfull that you put up with his s*** that he will do anything for you.
Hope this helps.
Thank you this helped so much.
But how do I deal with it, it breaks my heart.
