My girlfriend of 14 months kicked out my dog, so I think I'm going to break up with her.
Did you know her before she kicked your dog out?
Yeah we got together later.
This sounds like a complicated situation. You need to speak with you partner as it is good to consider the feelings of your partner when you make decisions.
Yes, I need to talk to my girlfriend about her actions.
Yes, that's good. Hopefully you will listen to each other and find a good solution to this problem.
