It may seem ok on the surface, but it rarely ends up ok. You guys have had a lot of troubles going on, and do you really want to add this into the mix too? If it were me, I'd try and sort things out at home first, and then decide what do to in the future. You may end up having feelings for another woman which will make things very confusing, and she may end up regretting what she said and it cause all sorts of negativity. I don't think its all that healthy personally speaking, and it could cause more problems that it appeared initially to solve.
