Speaking as someone on the receiving end of constant phone calls from rehab while he tried to
force me to wait for/on him with bated breath, I absolutely agree with this.
Only do what you can afford. And if you can't afford to pay for some way for him to contact you, then don't. He needs to spend his time worrying about his own recovery, rather than worrying about calling you. (I don't mean that to sound harsh. The more time he spends trying to call you, though, the less time he's spending on his own recovery.)
