it sounds like his rehab have just doped him up and sent him home after the 2 weeks-no aftercare or support etc-that may be what he needs-as you say, if he wants it then he will go and get it-no harm in pointing out the obvious to him-in a gentle way-if it can save the child living with mum and seeing dad once a week or whatever then it's worth the treck-if i would have got the help i needed when i needed it then maybe i wouldnt be 38, living alone with my son-i would still have my family-been 8 years now and it's horrible-if someone would have helped me get help back then i wouldn't be where i am now-am happy with my son and we have a decent life-but sometimes he wants his mum, as will the child want his dad-that's my point-get help from outside before it's too late-it's too late for me-unfortunately
