My relationship started 8 months ago, with my boyfriend and his wife inviting me into their marriage making me his girlfriend. Not only is this the first crazy relationship I have been in it gets crazier, his wife had her own girlfriend on a month. Well now we have all gone on to our own relationships; me and him live in our own place together and his wife is living with her girlfriend. But now it seems like he is hiding things from me regarding his wife. I don't care that they talk or see each other because I know for the divorce its necessary but he is lying and hiding things. I'm not sure really how to take it or bring it up in conversation to see why he is hiding things. Please help.
