I don’t think there is much of a thought process. Or at least his actions are emotionally consistent but not intellectual consistent.

Being broken up with is painful, either as a sense of loss or as ego pain.

In order to make both disappear he needs to get back with you, but if he only cares about making the ego pain disappear he just needs to convince himself he is better off without you, and the easy way to convince yourself of something is to convince others.

So both actions are just him responding to (what I assume is) ego pain, neither of them are necessarily informed by his true perception of who you are.

Edit: none of this excuses his actions btw, it’s meant as a way to understand why he is saying cruel things and to understand that the things he is saying have no basis in reality.

How did your boyfriend talk about you to third parties while you were together?

They are arguing the definitions with someone who was “arguing” with someone who lived through the reality

Electric cars allow carbon emissions from personal transport to fall in step with the carbon emissions from energy generation.

Every solar panel, wind turbine, hydro plant, nuclear plant etc which comes online makes all EVs a bit cleaner, but does very little for internal combustion engine cars (acronyming that feels weird now)

Ideally we would have fewer or no cars, but I get that I’m very lucky to live in a major metropolitan area with good public transport and that’s why I don’t need a car, but that’s not true for everyone.

It is significantly easier to move people from combustion to electric cars than it would be to build robust public transport everywhere and change the habits of everyone in the country.

I think it’s counter productive to shame people for taking a positive step for the environment just because it’s not a total solution. People doing good should be praised not shamed, even if it’s a small good, especially if it’s a small good that might lead to them making further positive changes.
