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

So here is the story. Me and my girlfriend met each other in September 2014. We got along very quickly, and the romance was there from day 1. After 2 months of dating and getting to know one another, we went into a relationship(she was eager to make it official before me, as she was "crazy about me" but i wanted to make sure this was "real"). in the first 2-3 months we had a blast, made each other laugh all the time, we was crazy in love and feelings escalated quickly. 

However, the last month things changed a little from her side. The cute goodnight text comes less frequent. She wont send me as many spontaneous text like "Thinking about you" etc anymore. And i can't remember the last time she initiated a kiss or cuddling. So i sat down and had a talk with her. Apparently her honeymoon phase was over very quick and her feelings for me started to decline a little. This happened like 2-3 months in our relationship so we've been hooking up for 4+ months in total. I know this is common, as the honeymoon phase rarely last forever. BUT, i think it ended extremely quickly. She is super frustrated about this because doesn't know why it happened, and she feels she should still be in that "lovebubble". And that i'm the best guy ever and no one is like me. She still have feelings for me, and even said she loves me. They are just not as strong as when we started dating, and they stagnated after the initial honeymoonphase she said. She also said that she is still seeing a future with me, since there still are feelings there. so that's a relief. I just don't know how to process this. I'm worried her feelings will continue to decline and she will move on.

Anyone with similar experiences? any comment/tip would be helpful.
<bot>: My girlfriends honeymoon phase disappeared very quickly. Feelings declined and stagnated, but she still says she wanna be with me. Should i be worried her feelings will keep declining?
