So, okay, here's a healthy-relationship guide to normal/acceptable vs not. Just in some things, obviously.
Being difficult to live with. Everyone is difficult to live with to some extent. People in general are annoying and we're all different, we've grown up in different families, so you've got your ideas of how to do things and he's got his. Maybe one person thinks that it's best to wash up with a sponge under running water and the other thinks that's incredibly wasteful and it's better to wash up in a tub with a brush and a cloth. Neither is wrong but it's annoying to the other. Or, one person likes to have windows open whereas the other likes to have them closed. That kind of thing is the normal kind of annoying, other person thing. The only way to avoid this would be to live with one of your siblings. There is the second point of how annoying it is to live with someone! If you have siblings you probably used to fight and wind each other up on occasion, just because it's annoying to be in close proximity to somebody. (Although, if your siblings were full on violent, mean or cruel, then that's not acceptable in adult relationships)
All of these above things are fine. You compromise, or you studiously ignore the other's washing up method, or you have a silent ongoing, good-natured battle about which way to put the toilet roll, etc.
What is not okay - arguing, putting someone down, belittling, name calling. Bullying you into doing things "their way". It's not okay to expect someone to have no preferences or opinions or feelings of their own. It's not "difficult to live with" to have a different opinion or idea about how to do something or what to do or how to deal with a situation. It's fine, it's normal, he needs to accept you are a person too.
Do you want to share what the argument was about for an outsider's perspective?
