But you aren't in a relationship with either but you are pretty much more than friends with both people? (Doing things that are 'relationship material' rather than simply hanging out as a date... if that makes sense.)
And the two people do not know that you are seeing either one of them at the same time but you want to make a decision which person you want to have as your significant other.

It's not technically cheating, but only because you haven't officially said you are in a relationship with either of them, which you kinda are. I believe that if you are interested in 2 people it's OK to see them individually as friends, however as soon as one of those relationships escalates, you owe it to everyone involved to be upfront and honest about what is happening so you don't hurt anyone more than you have to.1
