Hi! Free roam isn’t always the best choice especially if it’s not the safest, and not conducive to you both living happily ever after. As long as she has plenty of space for exercise and lots of attention, she can be perfectly happy in an enclosure.
I’ve had great success with these panels: https://www.amazon.com/Tespo-Playpen-Portable-Plastic-Transparent/dp/B06XTG94TH/ref=sr_1_1?dchild=1&keywords=playpen+panels&qid=1588642589&sr=8-1
This is about 22 sq feet of space and 28 inches high….if you think your bun can clear 28 inches, out can attach a second level. There are quite a few different options and sizes. These are completely customizable to your space and size of your bunny. These keep by bun safe and prevent my young daughter for trying to handle him if I’m not around to keep an eye on them. If you have a larger rabbit, I’d recommend zip tying panels to a dog kennel or something heavy enough she can’t lift.
You can also get a basic x pen: https://www.amazon.com/gp/product/B002908DX0/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1
I got two of these and attached them together for garden playtime.
Just make sure when shopping to make sure the space between bars is not too wide for a bunny, and keep in mind they can and will push toys and hideouts to use as an “escape ladder” if your enclosure doesn’t have a top. I hope this helps!
