<human>: Can you condense the text into a few key points?

I'm extremely confused. Her and I have been together for almost 2 years. I proposed over Christmas. Everything was perfect. Our relationship was perfect. We have been living together for a year now and now that we are enraged, I'm noticing some changes. I make more than her so we proportion the bills accordingly.  As for chores, I do laundry she cleans the kitchen. Everything else is fairly cleaned by us on a day to day basis. The problem is she I slowly getting  more and more lazy. She doesn't pay bills until the last minute and the cleaning is rarely happening. She has become a stay at home lazy person. The second she gets home from work she puts on sweats and never goes anywhere. I'm an active person and go to the gym regularly. She guilt trips me for leaving her every time. She refuses to go out with me to places, I enjoy the slightest amount of time together, even going to the grocery store. She refuses. 

In addition to all that...have you ever felt like someone just wasn't attracted to you? She has admitted to me before (when we were first dating) that she usually dates, as she put it, really really attractive guys. Emphasizing I wasn't. I can 110% say that I feel like she is settling for me. I'm a safe bet in a relationship for her. She is barely content. 

So all this is just pestering me. When a girl I've been friends with forever lets go and confesses her love for me. This friend (19f) and I have been really close for years. We have extremely similar personalities, share a lot of common interests and are extremely attracted to each other. We click. Simply enough. 

Now I've been pondering everything and am planning on making a road tonight for the weekend to go see my friend. My fiancé doesn't know why I'm going. I don't want to have sex with this girl. (I do but I know it would cloud my thoughts).  I still don't know what to do. Should I go? What should I do? Help me please. Is it all Me being crazy?
<bot>: me (23m) and fiancé (23f) having a terrible engagement. She is getting lazy. I'm having doubts and thoughts about a new girl. Am I being crazy?
