Dream of father, girlfriend, married

I dreamed that I was going in the street where used to live a girl who recently married. There was a new house which was not built until the end. We went in (I don't remember who was with me). Then I realized that was house of my best girlfriend s father in law. On the second floor were three bads: first was for my best friend, second for my ex, and the last one was for the guy I like now but we are not in contact. Then I remember we hangout (me and the the guy I like). I felt that it was the best time in my life. On the end, I had to go and we made some plans which I don't remember.
