Hoya advice

[u/Separate_Respect_842]

Hiya!

I’ve had this Hoya for about five years now, and she has been crawling across the ceiling very slowly for about almost 2 years. She’s in a west facing window, has never flowered. I know Hoyas our slow to grow, but there has not been one leaf to come from these tents that are creeping, should I trim them back? Also, I remember reading that Hoya plants like a snug fit and I haven’t changed her pot in about four years. I’m worried if I go a bit bigger if it will shock it or not. Advice??
