<human>: Can you give me a shortened version of the text?

So we have been together for the last 7 years which considering how young I was when we got together means that he was my first real relationship. We have been in an open relationship for the past 2 years(purely sexual, no emotional attachments with others). 

I'm just posting here for advice. I've fallen out of love with him, I don't know why. I just don't feel the same spark as I used to feel. I have no interest in having sex with him. I just find every little thing he does incredibly annoying. 

I don't know how to break up with him. We moved in together in August 2013, he moved away from his job and his family and everything he had to be with me. (I live in a city 3 hours away from where we are from for university). How can I break up with him when he's given up everything for me? 

I feel like a bitch, I spoke to him and he's convinced this all because I'm depressed again. I have tried to explain it's not and that I feel fine but he refuses to let me break up with him. I don't know what to do.
<bot>: Fallen out of love with partner of 7 years. He won't let me break up with him. What should I do?
