I bought a 110k bmw to impress my ex
Why do you want to impress you ex partner?
I want to show off my success so he regrets not being with me.
I can see what you're saying, but it is very low and immature to show off your wealth to impress your ex partner. You should find a new relationship to focus on and build that instead. Otherwise you are stuck in the past and cannot grow as a person.
Maybe I just wanted to piss off my ex.
Don't you think it is a rash and expensive decision to buy such a fancy care for this reason?
