What to do...

[Tink]

Lindsey, is it possible that he's a bit of a control freak?
If so, it's best to recognize it early.

When my dh and I were dating I had 3 adult german shepherds. He knew without being told that they weren't going anywhere. One of them got badly injured and required expensive surgery. After the surgery was done the hospital informed me that I couldn't take her home until I'd paid them in full. They would of course be charging me a boarding fee every day that she was there as well. When I was sitting home crying over it and trying to decide how I was going to afford to pay for it, HE went to the vet hosp, paid for it, and brought her home to me!

THIS is the kind of guy you want in your life for the long-term. He doesn't have to love your dog, but he should love you enough to accept that part of your life without making you feel you need to choose between the 2 of them.

I don't know what you should do, as it's a decision only you can make; but I'd definitely see it as a warning flag as to his true character.

I'm sorry you're going through this.
