@melancholic, although you may not be liable to bigamy, just make sure you know what you're getting into. if you say that he's now a faithful muslim, he may not be the same person as he was before. be sure you are ready to accept his religion and what it stands for. at any point, he may bring in a second, third and fourth wife. be sure you are ready for this. he may also prohibit and demand c.ertain things from you like convert to islam and behave in certain way, like wear burqa and hijab to cover your whole person, isolate yourself from friends and stay home. wahabi islam, which is what saudi practices, is the most backward, oppressive and barbaric kind of islam. it really depends on how serious he is with islam. this is just an unsolicited advice from a concern stranger. wish you the best in whatever you decide.
