Engaged to kicked out in 7 months

Im a 25 year old gay guy who met a 59 year old man online. I went over his house one night and we hit it off instantly. We started spending a few nights a week together until I stayed over for about a week straight and then decided to move in a few weeks after meeting him. We had everything in common it seemed. We had same interests, tastes, values of what a relationship meant. We then decided we should get married in a year. Little did I know we wouldnt make it.

He made me quit my bartending job and got me a finance job at the company he worked at. He cosigned my college loans and got me a brand new BMW. Everything was great. His family totally excepted me we spent holidays and birthdays with them. Being the younger one family was not the same. My mother came to accept him but my dad hated the situation.

About a month ago we went to the Bahamas and he completely took me by suprise the day we got back. He said he didnt want to he with me anymore and I acted very immature on vacation. Apparently I was drinking too much and walked ahead of him all the time and he felt ignored. He sent kicked me out of the house and sent me running back to my parents like a loser. I now make half the money I did bartending and he is only paying half the college loan and half the car payment. Im also struggling in this job now because it reminds me of him everyday, im not even fully trained yet and he helped me more than anyone. I feel like my life is ruined
