A work colleague has been divorced from her husband for three or four years. He is originally from overseas so, for a while, returned there, during which time there was little contact with their children (aged 4 and 6). He has since been back, they have tried to reconcile but to no avail, and so now they're in a kind of limbo with regard to his living situation and contact with the children, which is getting her down.
He is a student at the moment, so can't afford more than to rent a room. The children can't come and stay overnight where he's lodging (and she doesn't think he'd want them overnight anyway, as they'd be 'hard work'). He is paying her next to no maintenance (presumably because he's a student). So, in order to see the children, he frequently visits and stays over at her home.
From what she has said, she feels suffocated by him constantly being around, and is caught in a difficult position whereby if she didn't let him come to visit/stay, he probably wouldn't see much of the children (which she wouldn't want for their sakes), but by him visiting/staying, he's forever under her feet, there are no boundaries or closure on the relationship, it's potentially confusing for the kids, and she's getting very little time to herself. Also, he is eating her food and making himself quite at home, which I think she feels resentful about because she's paying for it all and he's contributing next to nothing.
What options has she got for moving their contact arrangement on without it meaning the kids don't see much of their dad any more? I've suggested he lodges somewhere where children are welcome (a friend's ex does this) - but she can't make him, can she?
Grateful for any ideas. Thanks.
