<human>: Weve only been dating for about 7 months. 

 Background- boyfriend had to put down his 15 year old dog today. Ive been through the same thing and I also did my fair share of crying over the dog.

Yesterday, as usual, a lot of people were over his house (he lives with social roommates) mostly so say farewell to the dog. He casually mentions in front of me that earlier that day hed shot a groundhog with a BB gun "because ground hogs are assholes (WTF?!) in the butt twice and it ran off.

I expressed my horror at that and he was mildly suprised I was even upset. I didnt harp on it or yell about it because of the dog situation. Hes upset at me for being upset at him over the groundhog at a time like this. (to be fair, the dog passing away is really traumatic for him) 

Im no vegetarian or animal rights nutjub, ill admit that, but I work at an animal shelter and have seen my fair share of pitbulls littered with infected, festering bb shots all over their bodies. Its horrific, and theres some innocent groundhog running around with bullets in its backside

It kind of just brought up how much we apparently didnt know eachother- that he could be so dismissive and cruel and uncaring about it, and that he would think id be fine with it. 

Im still not bringing it up because hes grieving right now, but I cant just sit here thinking about it forever. Its all i think about when i look at him, and its so frustrating blindly comforting him about the loss of one animal while all i can think about is the other. 

I dont know what to do-if anything. Am i overreacting?

Can you give me a shortened version of the text?
<bot>: Boyfriend shot a groundhog with a bb gun. im appalled but cant express it because hes grieving over his dog. Not sure if im overreacting.
