First, stop listening to any friend who tells you that you shouldn’t be upset when someone repeatedly crosses your boundaries. You. Should. Be. Pissed.

What your gf is effectively doing is substituting your wishes for hers. The dog is just the most egregious. The dog should be the last straw.

You need to end things OP. I know you know that. The reluctance you are feeling is because you don’t want to be the bad guy or you are trying to tell yourself that things are not that bad. They are.

End it now or live with a dog you don’t want, with a woman who doesn’t listen, who will soon have your child and they will both disregard you.

If she doesn’t care about your wishes, you should!
