It's good to go into these situations fully armed with knowledge about addiction and the behaviors that addicts share, don't you agree? Then you can be on the look out so that issues that come up don't catch you off guard.
Addicts often start dropping hints that they are contemplating a relapse long before they actually relapse. And it's very common for addicts to set up their partners so they can blame their relapse on their loved ones.
However, it's always good to remember that we are not responsible for the behavior of others. Life has its ups and downs. We need to be able to deal with life on lifes terms. If someone wants to stay clean, it's a requirement.
