If I were you, I would make contact. I suspect because you have been pondering it for such a long time, if you didn't do it you will always be wondering. You don't have to make the first contact with bilby. Meet her yourself, check out the situation. Things may have changed and you may be glad that you did. Things may have not changed and you can then choose to not let bilby meet her after all. Of course you need to make up your own mind, but that is what I would do.
