Child support? Does he have a child with this ex, or another ex? If he has a child with her, is it her and the child who visit?
It sounds odd to me - but then a lot of us lead unusual lives, so I wouldn't hold that against him! Why not insist on meeting this ex on web cam. If he refuses I would say either there is something going on, or he is not proud of you.
Good luck.
