From my experience it's difficult to make use of a language partner. It's also questionable if you can learn much.
You like already reading - read more. Reading is a VERY GOOD way to learn a language. Just make sure you read something that is not too much above your level, and also which is interesting to you.
Movies, TV is good too - what them with English subtitles - and English subtitles ONLY.
I mean to study (again) 汉语, but level is very poor, maybe HSK 2-3. I would love to watch 三体 (the Chinese TV series, not the Netflix one) but that seems way way way above my level.
加油!
