My friend has 2 children with her ex partner, he's basically a no hoper and has trouble holding down a job, smokes too much weed and gambles too much but I think a lot of this is down to depression he won't admit to and he is essentially a nice guy, and he loves his kids and he currently sees them at least once a week, always at my friend's house as he has no stable place to stay and is often sofa surfing. At various points over the years he has disappeared for a few weeks with no contact with my friend or the kids and worries everyone. He has gone awol again now and has currently been missing for nearly 3 weeks, the kids are older now and are asking after him and my friend doesn't know what to say anymore.
His family want nothing to do with him (which I think is very sad) except his mum who has sporadic contact but lives very far away and when my friend has told her about the situation she has been no help.
I personally think my friend should just cut him out of her life for good but she finds it hard because the kids do love him. He gives her no money so he doesn't contribute that way.
I've told her she should report him missing but we know he's probably not got to any harm and is just bumming about somewhere.
How would you move forward with this situation?
Thanks sorry for long post.
