So, what I'm going to say next is just a preliminary guess based on the information you gave me, which may not be accurate.
I think your desire to cross the bridge may have something to do with your desire to do business in your life. You want to cross the bridge, but your car skidded because of ice, which means you want to do business, but your family objected and the process was not smooth. The car fell off the bridge, and you are still on the bridge, which means that you don't give up and are still doing business. When your family is against you, you want someone to support you. Your cousin and ex-girlfriend should have supported some of your decisions at some point, so you subconsciously thought of them at this time, so they stood beside you and stood on the bridge with you.
That's all for now. If you want to know anything else, just ask. I will try my best.
