I understand the concern over being seen as the reason that he left his marriage. Especially if you come from a devout Catholic family. You have to understand though, that the morals that your family is displaying, thus causing them to be upset, are from 50 years ago... You are not the homewrecker out to destroy good happy families. And your bf left his wife and his marriage because of his wife and his marriage, not because of you. Unless he has said otherwise, believe that.
And, I can't believe I am writing this but, who cares what other people think? If you love him and he loves you and you want to be together, be together. make sure he gets that divorce as soon as possible though. It will make things much easier for you, both legally and emotionally.
Good luck.
