maybe you have this addiction because you love him and need him toooooo much,but at the same time it could be a problem in the relationship coz addictions are not good..you know....

Ride that going great wave as long as you can - you're right, nothing lasts forever (or nearly long enough). If you've given the guy a deadline don't sweat it until the deadline. You can waste an awful lot of energy stressing on what MIGHT happen or what COULD or SHOULD happen. Just enjoy the positiveness (word?) of the moment and let things develop. Of course, if you've given him multiple chances in the past and he doesn't come through this time you need to stick to your guns and if necessary move on. Life really does go on and you'll survive and who knows, maybe even be a lot happier without all the drama.

Just remember, if you set a deadline and then let him ignore it you have set a pattern and he will never feel he needs to get his shit together. You want him forever the way he is right now? I think not. Don't turn this relationship into a one-sided affair. Addicts aren't really a whole lot of fun to hang around with - you want to turn into that?
