Do I need to sue my wholesaler?

[Crystal Wilson]

About 8 months ago I met a wholesaler. I had 25k in a HELOC. He showed me a house to buy in the suburbs of Denver to try and do my first fix and flip. My dad was going to co sign that's the only way I could get the place. My dad backed out of co signing so I could no longer finance the place so I backed out before closing. Wholesaler kept my 5k as commission. He told me its OK well do another deal and you will make money. So he sends me more homes, I pick one. We look at it and plan that we will go 5050 on it. He keeps picking up large checks from me. 8k, 5k, 4k, 1200. For earnest, materials, his commission. Till I have given him all 25k. Its been over 8 months and still hasn't closed. Every week he tells me this monday we will close. But it never happens. At this point I know the house will never close. I need my money back. What should I do?
