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

My boyfriend got upset with me today, saying I start a lot of arguments and he feels like I'm just picking fights.  He seemed really fed up with it and he's a very patient person usually, so it scares me when he gets like that.  He got upset about this before, a year or two ago, and I thought I got better at it.  I had been truly convinced at that time that he was going to leave me if we kept fighting, so every time he did something that upset me, I tried to look at him and think about my love for him and ask myself if it was worth jeopardizing our entire relationship over.  It was pretty effective for the most part, even if I constantly feared losing him, but eventually I started to realize that he had never planned to leave me and maybe I got too comfortable again.  I don't know.  It's just so unnerving to be told I pick fights when I hate fighting as much as he does.  I'm afraid something's wrong with me. I've heard people talk about their exes, saying the girls were just in it to cause drama and be manipulative.  What if he ends up feeling that way about me?  We've been together for 7 years, and he's the most patient and understanding person I've ever met.  We've told each other we'll be together for the rest of our lives, but I'm so scared I'll ruin it and chase away the best thing that ever happened to me.  What do I do?
<bot>: My boyfriend feels like I pick fights all the time even though I don't want to fight with him either, and I'm not sure how to change.
