Hi your story is as mine as you wrote it, you wrote a good explanation of how you feel, is how i feel.
Only difference is, unlike yourself this man did not buy me expensive gifts, in fact he played me there too, so many manipulative ways to get money from ME, even knowing i was on a low income.
But i understand your torment, anger. as i feel totally broken to have had everything and lost everything.
So do not feel you are alone,. talk here x
I cannot even think about starting a relationship again as this was the final one as far as i concerned, but that does not mean you cannot.
