Your story rings huge alarm bells for me. I hope I am wrong, and your boyfriend is just clueless. But in reality, someone who moves into a lover's or friend's place and shows no intent of sharing the rent is not an honest person. You have a good heart and perhaps it never really occured to you that you were being taken advantage of, you just experienced it as "losing the spark".

I had a problem with a woman, but men do it as well. I let her in for a few weeks because she was going to be homeless otherwise. She stayed 6 months, and even after she got a job, she never paid a penny. She acted like my best friend when she was with me, but was telling other people rather bizzare lies of how I was oppressing her and taking advantage of her. After I gave her a notice to move out, she started "looking for a room" and kept coming back with stories of unbelievably horrible places and people she was running into. Then it got worse, but I don't want to scare you.

I hope he moves out soon and without an incident. Keep things calm and polite and make sure he is really looking for a place. I'll keep my fingers crossed. If you have some friends or family members may be a good idea for them to pay you a visit.

I am very sorry you are feeling heartbroken, that's the part that goes with having a good heart. Take that as a ray of hope for the future. You are a loving person and that will attract to you someone who will love you, not just those who would want to take advantage.
