Relationships with exes post breakup

Im not sure if this is just me but I would like to break up with someone and everything go back to how things were before. Its just so awkward after you break up, neither person knows how to act or what to say. Sometimes you think it would just be easier to just ignore and stay away from each other then be in weird situations or feel uncomfortable around them. Also, dating people you were very good friends with then it not working out just sucks because then you have no relationship and you have lost your good friend. Relationships seem good at first but maybe there not worth working for.
