Even if you think you still love this person--like forever and ever-- believe me, you'll get over it by next June, once you cut the crap off with the current situation. Put a period at the end of your decision, once you make one. There are more interesting things to do in life than putting up with someone else's life style you don't particularly want to share, or with anyone who fails to respect you. You are being used, and she's obviously ready to dump you anyway. Retreat is not always cowardly; even in war, it's sometimes the most efficient battle plan.
Advice is like kissing: it costs nothing and it's a pleasant thing to do. (George Bernard Shaw)
