What happens if my chapter 7 bankruptcy was changed to a chapter 13?

I'm in a big problem. I hired an attorney to help me file a chapter 7. The whole chapter 7 was dragged out to over a year and half. When I first contacted the attorney to help me file chapter 7 I no job and was filing because of debt for credit cards and a foreclosure property. when everything was set up and ready to sign my petition I told them I would be out of town for a month because I was getting married and they said we can take care of it when I got back. when I got back the paralegal told me there was a big problem that she just realized I was married now. After I specifically told them I was going to get married. I would have to change my chapter 7 to a chapter 13 I told them I don't want to do a chapter 13 they told me I have no other choice because no I have combine my wife and I income. I'm afraid of doing a chapter 13 because I find myself with no job again and fear I will not be able to pay back the debt doing a chapter 13. I am very confused and just have no luck with any attorneys I've work with now and in the past. The property that I had go into foreclosure was handled by another attorney I was working with and they forgot to response to court notice so it went into foreclosure. the only thing they could tell me was sorry. I had a buyer for the property and was setup for short sell they put in a offer and everything. I ask myself if there is anybody that can really help me.
