<human>: Give me the gist of the text in a nutshell

My boyfriend and I have been together for a few months shy of 3 years. We are completely in love. We've been best friends since day 1, and he is literally the guy version of myself. Through our relationship, my boyfriend (let's call him Adrian) has been working full time. I dropped out of high school at 16, and have been home nannying my younger brother for only $100 dollars a week. I have no car or high school diploma yet. I've been working towards a GED and have been promised a car when I acquire it. But, since I dropped out of school I have become increasingly lazy and I focus on my relationship, rather than working on a GED. Adrian and I have been planning on getting married late next year. But, I have become very nitpicking lately because I am home most of the time without a car and nannying. I don't like Adrian to go out with his friends whom I don't 100% trust, though info trust him. Yesterday morning, he told me he wants to have a break in our relationship and we are NOT broken up. According to him, he needs time apart because he's "losing faith and enthusiasm in our relationship", though his "feelings for me have NOT changed". I never thought my laziness and bad habits would make it come down to this. We are supposed to talk in a week to see how he feels. I'm completely heartbroken. I want him to stay more than anything and I feel like this is completely my fault. What can I do? Is there even anything I can do? Help! :( (Sorry for the long post!)
<bot>: Pushed away long term full-time working boyfriend with lazy habits and lack of reasonableness. He feels worn out and lost enthusiasm. Took a break and I'm scared he will leave for good.
