Is it just me?

Just want to know if these is me or not. I moved islands for a new job and my partner and I both agreed that we'd sell his car if we needed it for a bond for a new house. I found a house that the agent was discussing with me and we started talking about a bond. I then found out my partner had traded that car in and put himself on a loan for another. It's been 2 weeks. I'm angry, I'm frustrated and he thinks I'm feeling this why because he thinks I thought he couldn't afford the loan? He didn't tell me, until 2 days after he did it. What would you do and how would you feel?
