Well good sir I think I may know your issue if you feel your level isn't quite high enough for your liking. Seeing you play a melee build with a tad bit of magic I'll assume your major skills are either Light/Heavy armor, One/Two handed Block and Restoration. Now this is a good build but I bet by level 42 your Offensive skill is 100, along with your armor skill. And potentially your Block and restoration are quite high, if you use them frequently. The issue here is that with your most commonly used skills reaching there max, the skill levels come slower, and in turn, the levels come slower. But this is not the end of your characters leveling, all you need to do is level up some of the skills you ignore, perhaps Alchemy or Speech? Now this may seem difficult, but is actually quite easy with a bit of research and action.
For example I will give some tips on how to level the skills I mentioned before, Alchemy and Speech.
Alchemy: I myself am no expert Alchemist, far from it in every way , but I have used it to help quicken the pace of leveling at later levels. The trick with leveling Alchemy is the value of created potions, the higher the potions value, the more Experience you will get towards the skill. There are several helpful guides located on the Forums here that will help you become a master Alchemist. This post for example, is great for potion values --

Speech: Leveling this skill is actually very easy, Although the method I am about to recommend may be considered a exploit. If you head to Riften, you may know the location of the Black Briar Meadery. Inside at the front counter is a Wood elf named Ungrien. Now if you begin conversation with Ungrien, you can ask him about Maven Black Briar, which will give you the option to persuade or bribe him. This conversation can be repeated over and over leveling speech incredibly fast compared to the normal rate.
I hope this helps speed up your leveling process mate, Should you decide to do so!
