<human>: This happened around September. 

I have this Cartier money clip I bought from Japan for around 200 USD. I had left it on the dining table with all my stuff. 

We were having a get together and we decided to clear up the table with my stuff on it and my apartment mate was helping. 

When I was turned around putting stuff away my apartment mate tossed my money clip onto my roommate's desk where it hit a pot and dented the clip. 
He offered to pay for another one because he didn't know how much it cost but I was so mad that I just told him that it's too expensive. In my head at the time I thought that I didn't want to risk the friendship over money. 

I tried pretty hard to just write it off but that dent in the clip and his stupidity in throwing my clip was bothering me. 

Later on in the year in an unrelated incident, we're not on speaking terms and we're not friends anymore. He's decided to stop talking to me and has been a real bitch to me since then and I remembered about my clip. 

I wanted to get my clip repaired and ask him to pay for the repairs. 

Should I go along with this and how should I do it?

Provide a brief overview of the text.
<bot>: My nightmare of an apartment mate damaged my expensive money clip when we were kind of friends. We are not friends anymore and I want him to pay for repair costs
