I feel really bad for your Heartache. It seems like she took advantage of you in multiple ways when she moved in with you; free rent, free food, and someone she could emotionally manipulate.

Perhaps next time you meet someone online, take it REALLY slow and just visit each other until one of you is emotionally and financially ready to move in with the other person.

It sounds like you and she both made mistakes but the real issue here is that you both had different priorities from the start; hers was to go to nursing school and yours was to be in a relationship with her. You were her second fiddle b/c nursing school was her priority; you were just the option she was sleeping with who paid her rent. Your priority was to be in a relationship with her, and when you asked her to be in that relationship, she chose her family and nursing school over you. That is why neither of you are compatible with each other, as far as I can tell.

Really sorry this happened to you. 2 years of your life is a good chunk of time to invest in being in a relationship.
