Am I being petty about name calling?

[Unicorns41]

I have been with my partner for seven years, engaged for two and own our own home for three years.
Mostly we are pretty happy however we have these very what I would call petty arguments that descend into worse arguments.
This morning is one example:

The council are working outside our house and over our driveway. My partner had left for work this morning just came back because he left something. In this time their lorry had parked across our driveway. As they were parked in the driveway he came in swearing and moaning about it.

I told him to calm down and that they’d be gone by this evening plus he was leaving anyway. He carried on moaning and I was getting annoyed as I was working from home and it was a particularly annoying task I was doing. Eventually I told him to go away (not very mature I know). He responded by saying that was a silly thing to do when someone was angry, as it would make them more annoyed. I told him although it’s annoying they are parked in front of the driveway he’s leaving anyway, they are working just outside our driveway and it’s not like parking is difficult in the street anyway.
He responded by marching out and muttering that I am an arsehole.
He then tried to make up with me but I refused because he’s called me a name again (this is an ongoing issue for me). When I refused he marched out calling me a child and I need to grow up.

I think the whole exchange was ridiculous between us. However I really hate being called names. He never misses a chance to call me something during an argument. In previous arguments he’s called me worse names and now I have a massive sore spot about it.
He grew up in an environment where name calling and arguing seems to have been normal and I explained ages ago why I hate it.
This only started happening when we moved in. It is less frequent and they are not so bad but I find it difficult not to react and fall out with him when it happens. Am I being petty?

I could never be with a man that thought it was acceptable to call me rude names. Arguing is one thing, but name calling is a whole other level, that shows a lack of respect and a feeling superiority over the person being called names. I dare say you’ll get posters saying you’re over reacting, but would you accept being called names in work, in front of potential children, having your child being called names? What if the builder knew your fiancé was pissed off and called him an arsehole or worse? Would he accept that as being acceptable?

That last sentence was a bit weird, but you get my drift.

You're not being petty but the arguments and nitpicking from both sides is a bit petty. When he started moaning about the lorry maybe you could have ignored it and just kept yourself busy out of his way. You shouldn't have to but it might be that you wind each other up quite often and that isn't good. Is this the man you'd like to share the rest of your life with?

You nitpick. He calls you names. How is this a healthy relationship?

I hate that term nit picking. It’s similar to nagging. The OP just wanted him to go, as she was working and he just wanted to continue complaining about a none issue.

That comment Eventually I told him to go away (not very mature I know). He responded by saying that was a silly thing to do when someone was angry, as it would make them more annoyed. is so childish. It’s akin to a five year old throwing a temper tantrum when they’re told NO.

I can't see you in any way at fault here. Your DP should direct his anger at the person or object annoying him and not have a tantrum that disturbs you: especially about such a trivial, non-issue.
Apart from that, the name calling is so so childish and if it's upsetting to you he needs to change. From your post it seems clear he thinks name-calling is ok so he doesn't see a need to change.
Unless you're happy to put up with this forever I suggest you get yourself out of this relationship.
