How should I (19M) process my gfs (18F) decision on making my dog’s death about her?

Hello Reddit! Me and my gf have been together for about 1.5 years and we’ve been doing fine besides some issues of course. We both live in separate homes with our parents and our usual interactions with each other are over FaceTime or text messages.

For context, I produce music on the side and have recently been involving myself in remix competitions thus causing me to not give my gf straight up attention during the night (the only time I can go and work on music). This only was recently and only has been happening for a couple days. I still call her but I can’t really talk because I have headphones on and have to listen to whatever I am creating of course.

The other day my family were given the responsibility of taking care of our grandparents two dogs while they were out of town. One of the dogs was very young and healthy while the other was old, blind, and deaf. Btw we have a pool in our backyard with no fence because we’re all grown and know how to swim. One day my parents and family came home to find that the old dog accidentally fell into the pool and drowned. Of course it was heartbreaking for all of us and we all cried our hearts out for this dog who was been with us all these years. We buried his body in our backyard and let our grandparents know who were also heartbroken.

Here’s where my gf comes in. While I’m grieving,I text her and let her know the situation and she expresses her condolences. I let her know that I don’t really want to call on the phone tonight because we just lost a family member and I just want some time to myself. Immediately after, she proceeds to tell me that I’ve been very distant and I have been making her feel alone recently. I defend myself by letting her know that we text and call every night ( we do). Her problem is that I don’t say goodnight and I don’t give nice texts for her to wake up too. I tell her that she is very inconsiderate to want to bring this up right now but she just kept on doubling down after this statement. By the way I totally understand where she is coming from and will listen to whatever she has to say, the only problem is that I just lost my dog to a gruesome death and she brings this up instead of leaving me be to grieve. She goes on and on and it’s making me more and more angrier because she’s not seeing the issue at all and keeps on going on about how I’ve been treating her as a “friend” lately. One thing I remember her saying is that I “shouldn’t be with her because I put family first”. First of all…. My damn dog died! Lots of guilt tripping, and off topic statements about how IM inconsiderate and she finally apologized for it. This isn’t the first time as she’s done something similar. I lost my dog last year in September and he’s been with me my whole life. I let her know that we’re gonna be looking at old videos and pictures of him while remembering him. Time goes by and she gets impatient with me being gone for so long and gets mad at me for it.

Reddit I just don’t know what to do and if I should break up or not? Is this breakup worthy? If it is how should I approach it? I still care and love her and I don’t wish to see her heartbreak but I just don’t think I can take such disrespect and inconsideration from her. The fact that she didn’t even second guess herself that this was a wrong time to bring it up is what bothers me. It felt as if even at such a terrible time like this, she still chose her feelings over mine. We’ve been doing fine but then she goes on and does this.

TL;DR: dog passed away horribly and during a time of griefing she thought it was appropriate to make it about herself
