If you are not married (not judging just going by facts) and the house belongs to her then you will have to move out anyhow. You have no legal right to it unless the two of you had papers drawn up stating otherwise.
How come you can't take the dogs with you? There was no way in heck I was giving up my dog - but my H gave her to me before we were married so it was mine. Take the dogs and go!
