If you think your bf has a wife

If you think your bf might be secretly married and living a wholeee separate life you don’t know about, would you find the wife on social media and ask them if that’s their husband? I think if she goes back and tell him it will draw a line between me and him. But he’s always ghosting me and I found a big clue that this can be his wife. If she says yes that’s her husband I won’t know how I’ll feel about it 😒
