It got to the point where I said loudly that I am going to take one of the pets to be treated at the vet I chose , and she was free to take the other pet to the one she wanted so we could see which did the better or best service at the best price . OP later admitted that he was yelling . Yelling that you ' ll take a pet there is not just getting a quotation . It sounds like she brought the pets to the relationship and she said she ' d pay to take both to the vet she wanted . There was nothing to compromise about because it ' s really none of his goddamn business how she spends her money on her own pets . He ' s the one who escalated by insisting on taking a pet to a vet who might be cheaper even though his GF was uncomfortable with their vet business based on how she was treated on the phone .
