First thing, I envy you, you are so lucky, to have an SO want you to gain! Awesome.
Next, your worst enemy right now is your age! In your early twenties, your metabolism is naturally high. You will find it easier to gain as you get older, trust me. I currenty struggle to stay at or under 200 lbs. and I exercise regularly etc. I am still in the military reserves,so I have to stay in shape. Hang in there the pounds will come!
