Try this one more time. I've typed out two messages so far and lost both - GRRR!

Okay, that is a rex but still rhizomatous. Rexes can be a bit more challenging but only in winter since they may/will go semi-dormant. I don't think that is what is happening here though.

A new plant will take time to adjust to its new living quarters so it may pout for a while but two months should be plenty of time to settle in. Did you repot recently? It looks like the plant is too deep in the soil - the rhizomes should be exposed.

You can remove the older leaves and restart those. Check other posts for propagating by leaf. It can be a challenge for the first few times until you get the hang of it.

Rexes (and rhizomatous) can take more light but can also do okay in dimmer situations too. More light - healthier plant but more water. Less light - leaves may get bigger but won't be vibrant - requires less water. Let the plant help you decide on where it is most happy.

A terrarium is another way of insuring a easier plant to take care of but it has its own set of issues as well.

Are you saying you have high humidity in your home too? Usually outdoors is a wonderful growing area for the warmer months if you want to go that route. Just make sure you do provide some shady area to begin with.

Here is an example of a rex I started by leaf pushing the top off this seed starting tray.
