It sure seems tricky... in a way she tries not to push, but she still want it. That only brings insecurity. Tho as far as we've seen she also hasnt said things like "i love u".
But the fact shes aware his also interested in another woman, regardless of why, sure isnt a healthy way to go about. She cant inquire since was private, but only because she dont have been given the right to do so or shown how far she can go. Its comfortable in a way, but still seems like they're on top of thin ice.
But they sure are really cute together, so much so that feels a huge waste if it gets messy.
