Boyfriends brother got a new puppy…but I’m not ready. AITAH?

So me (F28) and my boyfriend (M28) are long distance. We visit each other regularly. He lives with his mum and two brothers. Each of them has a dog and recently one of his brother’s dogs passed away. Now I have always been a big animal lover and I especially love dogs so I formed a quick bond with the dog, Jack. I form attachments really quickly with both animals and humans…and inanimate objects…maybe I have a problem 😅

Anyway I loved Jack over the year I’ve got to see him in little visits and this Thursday he died. I’ve been really sad and I cried a lot. I didn’t get to say goodbye and it was a pretty sudden death as he had only been ill for a week.

Today…which is Sunday, my boyfriend sends me a picture of his brother with a new puppy…

Jack isn’t even cold in the ground, I don’t think they even decided what to do with his body yet (cremation etc.) but they already have a new puppy.

Don’t get me wrong, we all grieve in our own way and this is completely their decision and I don’t have an issue with that but for me it all feels really soon and I personally just need more grieving time before I can be excited about their new puppy. Don’t get new wrong, the puppy is gorgeous and I know I’ll love it but right now I’m just not ready and I need more time. But my boyfriend doesn’t understand this. I know Jack wasn’t my dog and I know I maybe shouldn’t feel this attached but am I the asshole here?

Apologies for my crappy writing and I would like your genuine opinions because if I need to toughen up or change the way I’m thinking then I just need people to be honest with me about it. Thanks guys! And give all your puppers an ear scritch from me in memory of Jack 💕
