<human>: Can you give me the gist of the text in a nutshell?

I've been dating my current girlfriend since late last year, and before that and still now, I would consider her my best friend. We got along in ways that I didn't think were possible for someone like me and the day we started dating was one of the best days of my life, but now things aren't exactly the same considering we're dating but as a whole, I'm still me. She knew who I was coming into this and she hates being a person that wants to ask me to change but I have absolutely zero problem with changing because I see this as a problem in myself, but our relationship has been rocky when she has had to bring this up. 

I'm not sure if that's enough backstory to it or if it was even necessary at all considering I'm here for advice, but there it is.
<bot>: I'm pretty emotionless and laid back in my personality which has led to my girlfriend feeling like she is doing all the work and isn't loved. What are some ways I can really let her know how much she means to me?
