<human>: Condense the text into a few key points

Long time lurker, first time poster.  I've got quite the conflict brewing, and simply do not know what to do. 24 (F) has been with my boyfriend  (24) for 1.5 years.  Met in college, started dating end of senior year.  I moved to the bay area to be closer to him after 1 year of dating.  We have always been content, he is a kind and gentle man who has never treated me poorly, and just wants me to be happy.  I thought I was very happy with him.  However, after I moved here, I met a man from work (K).  We ended up getting very close, and I have strong feelings for K.  Nothing has happened, and my boyfriend knows about my feelings for K.  I love my boyfriend so much, but am so conflicted. K makes me happy as well, and is a very kind soul.  How do I know if this is a "honeymoon" phase, or if it could be something real?  What do I do?  I don't want to hurt anyone.  I don't have any friends here, and am incredibly lonely, seeing as I just moved to the area to be closer to my boyfriend.  Any help or advise would be appreciated.
<bot>: Have a boyfriend, am content with him, but there is another guy in my life that I am starting to be crazy about.  Advise from the kind souls of reddit please.
