Someone with better legal knowledge than me, will probably answer. But I
dont think you need to apply for
residence. You have
that already. For him to gain
contact now, you can just
refuse and the ball is in his court (literally). He would have to apply to
court for that, and unless he is in this country there is no chance of
that. He would have to attend court, and as previously stated, if and when
granted, it would be extremely slowly. If, as you say, he has drug issues,
do you think seriously, he would be able to get himself together to return
to the UK, find employment and then seek contact? I do know how you feel,
my X had drug plus alcohol issues and I still do not allow overnight
contact, as I can not be
sure he is dry/clean, but as time goes on, you will settle into a routine.
Either he is out of her life completely and you get along like that, or
contact and trust is built up. Try not to think too far away, lots of
things may change that you can not even imagine now.
