Dispute in business

I am Rajendra, i am an entrepreneur and working professional. 7 months back i have registered Pvt. Ltd. company. There are 2 director I and my wife. I had planned to operate it from home hence, was registered based on my home address. But later on my one of the friend shown interest in this by looking at my activity of business promotions. He is working in banking and insurance sector in private bank and i was working as freelancer(from 3 months, before that i was also working in company). My friend joined us and planed that he will make investment for business but will not join legally. I had team of unemployee fresher who were working with me from there home too on projects and assignments. Based our planning(me and my friend) we open up office on rent we hire employees and settle all other necessary things which were required to run an office and business. We were decided that my friend will do investment and also will manage sales of the business using his contacts. And i will manage administration part of the business like full time employee. He did investment indirectly that is into my personal account in same way i also did investment into business. After 7 months later we have shut down of our office due to loss in business and sold out some of the asset shared fund equally. We closed office based on this words that we will work on it part timely and will restart the office later again. Now after that i have joined some other company as employee started working here. Problem statement : Now, my friend asking his complete invested from me which he did, but it was not decided like that i will invest my time and intellectual. Infact to manage cash flow I also invested my money from pocket. I have not taken single salary in behalf my service from said business. He is denying as part into business and its planning. Whatever amount he transfer to me through NEFT is claiming as LOAN given to me. As sales of business was his responsibility but he never did it, now asking money which we were invested mutual understanding into business. I replied him that he will get his single penny from business itself but not from my personal asset or from my saving. I have never signed such promessery or legal documents as taking money as loan. So is am I liable to return money as a loan. Even we have not distributed share to him in company. Can he show transfer transaction as loan to me by showing bank statements. He cheated me putting involved alone me into business and now at the time of loss making me alone responsible. By giving money to him its look like double investment by me i have worked for free. But at this time i don't have money to return even if i want. I wanted to share profit with him from business not form personal salary. Sorry for long details.
