Fighting often comes from a lack of communication and misunderstanding. My boyfriend and I are a perfect example of this. Let's say he makes a comment about why he's angry, but due to my past experience with emotional abuse, I always take it personally and think he's blaming me. We fought a lot in the past because I never said anything about it. But when I explained to him why I react the way I do, we talked about it and decided that he needs to remind me that he's directing at me, but venting to me. And I have to do the part of reminding myself he's not mad at me.
So I would talk to your boyfriend about why you guys fight so much. Like what does he think the problem is? Make it a rule that if either of you get worked up during this conversation, to step away from one another and calm yourselves down. Keep your tone even and calm, and don't use accusatory statements (like "you always" or "when you...", as cliche as it sounds, I statements are key "I feel...when this happens... or "it makes me upset that..."). Essentially, this much fighting isn't healthy. Every couple argues of course, but if you're fighting every day, AND fighting over minor stuff, something needs to be done. A good rule my boyfriend and I came up with is we always ask ourselves if this is worth getting mad about. Most of the time, the answer is no. Minor stuff isn't worth being angry or starting an argument. Like yeah it may be annoying that you told him to call but he forgot, but it's not worth arguing. If it's an important issue, you two have to make the effort to talk about it calmly. And it may bug him when you blow bubbles with your gum, but again, not worth starting an argument. A lot of the time we get angry and frustrated with people because they're indirectly bothering us. But the world doesn't revolve around us. ya know? Just because one of you is having a bad day or woke up in a foul mood, doesn't mean the other has to walk on tiptoes or spend that day trying not to make you mad. Your emotions are your responsibility and it's up to each of you how you react to the emotions you're feeling.
