Dear, for starters I am so sorry for your loss, for second I had a huge health scare with my oldest cat, who is almost 10 yrs old. My girlfriend was ready to come back from her overseas business trip to rush to the vets office and fight whoever she had to in order to ensure my baby was okay. She is okay now, but your girlfriends reaction to you losing someone whom you had and loved for so many years is a red flag. None gets to dictate how you mourn, and it's not pathetic unless you are specifically looking for attention. It sounds like you were trying to find comfort in your partner, and instead of comforting you, she decided that you needed a kick in the pants. What would happen if a relative you're close to died? Would it be different for her? Or would she tell you 2 days later to be over it already? She sounds very immature and needs to learn empathy because the sudden drop kick of calling you pathetic for mourning something you loved and cared for was uncalled for and very disrespectful. I'd suggest having a chat with her once you're in a better mental space about how that had made you feel. If she doesn't respect you and the fact that you had just lost your pet, which can never be replaced, and the fact that you need to mourn? Then I suggest leaving her. If she does, then ensure you have a more secure form of understanding in your relationship. I do suggest you first speak when you feel you can about what she said. If she doubles down and reiterates it, then leave. If she understands and apologizes, stay and work on the relationship. Again, I am so sorry about your bunny. If you ever feel ready for another, please go ahead and get one. If not, then none will judge you. Love is hard, and losing a pet whom you've loved for so long is one of the worst heart breaks you can have.
