To say you still love them is to devalue the true meaning of love, which has to be built on trust and mutual respect. A decision will have to be taken, eventually. In the first place, it is essential that both of your alleged lovers know about each other, and what has been going on. If one insists that a choice is made… that can lead to a speedy resolution, one way or another. If all three parties agree to carry on as before… In that case, we are talking about a situation that I cannot empathize with. I cannot get inside the heads of such people. If they can make that work for them, then good luck to them. I am not going to moralize. To each their own. But I do not understand how that kind of love can work, not indefinitely.
