you have a complicated case so i the best answer is to see a local lawyer that can explain to you whats the steps you can do. But for me,personally, the first question i'll ask myself if i am you is,is that fact that your bf telling you is true,are there any proof,did he forwarded you any email conversation or txt that shows his wife or ex-gf threatening him of doing those actions that you mentioned against you or your bf? if there's nothing, then you better worry,not with the wife or the ex-gf , but your bf, coz he might be making this up just to reason out so he will not be obliged to go back in the philippines .You mentioned that he filed a divorce,then ask him to show you the lodgement receipt or any notification that there is really a lodgement that happened and if the wife doesn't want to sign it,then there should be a notification that shows the result of the filing. Thats just some few things anastacia, and there's a lot more to disect in your situation before you can get to that worrying of the other girls,but unfortunately,you need to deal with your bf first and start investigating if all he's saying are true,its not that am saying its all lies , but thats part of the process to find a solution to your problem. At this stage , you need to make sure that your problem is really a problem, not a problem crafted by your bf to serve his personal purpose.
