NEED TO MAKE A DECISION

So I’ve been with my fiancé for almost 10 years. We were suppose to buy a house this past October. Because of the housing market in our area that didn’t work out. He has decided to save more money to have a bigger down payment. We moved out our apartment and is staying with our parents separately. Lately this man has came into my life that I been with in the past. He know everything about what’s going on. He on the other hand wants to buy me a house. He wants to take me on a trip in about two weeks . I have been on a roller coaster with my fiancé and I said I am not putting up with this in 2021. I love my fiancé but I wondering if I need to start fresh or keep fighting for my current relationship.
