Don't dismiss your intuition because you think it's not a "good enough reason" to warrant a breakup. Most of us put up with soo much shit because we think we shouldn't break up for something "as stupid as that." Fuck that mindset. It will only get worse. Don't stand there watching the marginal disrespect build up every day until he either discards you or you have a breakdown because you can't tolerate it anymore.

Break up with him if you're tired of reminding him every day to do the dishes. Leave him the first time he raises his voice at you. If he mocks something you enjoy. If he's bad in bed, or simply not good enough. If he doesn't take your career as seriously as his. If you don't like the way he treats his family. If he didn't tell you he had kids early on. If he doesn't text you for a week. If he drinks more than you feel comfortable with. If he criticizes his ex. If he never apologizes. If he follows sexist people. If he always puts his friends before you. If he gives you a terrible birthday gift, or if he forgets about your date. I don't give a shit what it is. Break up with him. Don't explain, don't waste your energy on efforts that will be futile in the long run.

If it bothers you, it's important. It will not get better. If you don't like it now, you won't like it twenty years down the row, when the resentment is more rampant.
