To end 1 month relationship over this tiny thing

I’d have kicked him out the car there and then. Revolting 🤮

Bye bye to him!

You asked him not to.
You even write you begged him. To me this suggests you didn’t just ask him once, but repeatedly.
He still threw the can.

What happened after he tossed the can?

I would have stopped the car and told him to get out and pick it up.
It’s not just about tossing the can. It’s about the MASSiVE level of disrespect towards you. You asked him to not do something. You gave him a reason (which in all honesty should not be necessary because every Tom, Dick and Harry knows tossing a can =litter= an offence. By still doing it he totally disrespected you.
Please don’t say you went home and had sex with this twat after what happened.

Get rid, disgusting pig.

I couldn't be friends with anyone that litters, let alone date them.

That's not a tiny thing at all. That's appalling, 100% end things based on this. I'd have ended it just with him doing it, but the fact that you asked him not to and he still did. Awful.

Dump him. Imagine if you stayed with him, and in ten years time he throws his rubbish and you have to explain to your kids that littering is wrong “But Daddy throws his rubbish in the street” . Or he is doing schoolpick up and chucks his coke can on the floor in front of the other parents and teachers, or he is stopped by an enforcement officer while out with the family and fined on the spot.

It’s high time littering and dumping and flytipping were seen as anti social as spitting, speeding and drink driving. It puts up the cost of keeping streets and neighbourhoods clean and safe for everyone, shows contempt for the environment and wildlife, and shows a level of selfishness and self importance that probably leaks into other areas of life.

Sorry for the rant! I will carefully climb down from my high horse now.

Only a month in? End it.

It's not only what he did but that he ignored your request beforehand not to.

Absolutely end it. Who does that? I don't know anyone that would do that. Appalling.

Best that you found out early on. Good luck with the next one OP

Ho Ho HO!

I would have pulled over, pick up the can and told him to get out of my car. No arguments. Bye.

Huge red flag. What a git. Thank goodness you found out early. Easy enough to move on at this stage. Get rid.

Ew. I would absolutely end it over that! Huge red flags being flown in terms of his lack of respect for you, your property and the environment.

absolute gutter behaviour.

Oh my god even kids don’t behave like this. Why should he expect other people to pick his rubbish up? Why does he want to live in an area which is a dump?

Speaks volumes to how he will treat his home honestly tbh. Gross.

You said it yourself: no morals. Throw him out OP!

Have you confronted him? What did he say?
Awful behaviour, not cool.
It would definitely give me the ick too...

That’s such a weird thing for an adult to do. Was he drunk?

Unless you are really keen, and he is perfect in every other way I'd kick him to the kerb. It's not so much the litter lout thing (although, ugh) but you specifically asked him not to do it and he did it anyway- couple of years down the line you could be begging him not to hit you again, rather than not to litter.

He’s a dick

Icks are there for good reason, run for the hills before you're in too deep!

I absolutely would dump him, nor for throwing the can in and of itself ( though that does show something about him) but for not listening to my request that he not do this.

Doing what you asked in that instance would have cost him absolutely nothing and wpuld cause him practically no inconvenience yet he openly ignored your request.

What dies that say about how much he respects and values your opinion and about how much he wants to.please you or make you happy?

This is not a nice man and he is clearly showing you that .

Get rid of him.

This is shocking to me.

If you keep him he will do this behaviour in your home.

If he can’t see what’s wrong with that I’d end the relationship. Disgusting behaviour and shows complete lack of respect! I’d be certain things will only get worse!

Pushing a "small' boundary would be a red flag for me. It was your car, you asked him not to.
