Dogmama- Hi and welcome. 1) Get to an alanon meeting. You need support and to be able to separate yourself from the addict. 2) An addict will say ANYTHING to get what he/she wants. Words are absolutely meaningless when an addict is still using. Intentions are just that, intentions. When the guy is done w/ rehab, commits to a program of sobriety, then you can consider what and if you want out of this. If you truly love this person, stay away from him and let him get the help that he needs.
Hello and welcome. Addicts lie and manipulate, they will try to make you feel guilty and responsible for things they do and don't do. i would absolutely not believe him or trust him at this point. He needs to get clean, sober. Then remain in recovery for sometime before I would consider seeing him again. Keep your distance at this point.
I have to agree with jifmoc, an alanon meeting would be helpful.
The idea that you feel that you should sleep with him so he won't feel rejected and therefore skip rehab is for lack of a better word silly. He's liable to be sky high when he comes over. What will you do if he hears voices and becomes dangerous. People who are hearing and or seeing things that aren't there are not safe to be around.
Also, as the others have said, addicts will say anything and everything to get what they want. They're always about to get clean but there's some kind of reason it isn't now. Best for him and you that you separate yourself from it.
I'm sorry if this sounds harsh. But please look out for yourself. Meth is some serious stuff and what it does to people is really nasty.
