I feel as if i'm not improving

Sparring with people at your level is unproductive if he does things wrong sparring you, the you build the muscle memory to react to things that are not done correctly, a guy much better than you can slow down and go light while still doing things correctly, building proper habits and bringing along the person learning much quicker. Also boxing is a hands on sport, as long as you do the proper training with proper form you'll come along nicely, as long as you trainer shows you the correct form things will be fine.
