How to stay strong when in problems

Liam invited Mary to dinne with him that day but what was awaiting her was nice. As she entered the restaurant she immediately saw Liam and they started talking, Liam went to the washrooms and at this time was when Liam finally agreed to ask Mary to marry him. As most known relationships which have been together for 5 years, a girl could even say yes immediately but to Mary was different and she told Liam that he was rushing things and she was not ready to marry. Liam was so confused that he knelt there in shoked as people watched how Mary would embarrass a guy like that in a restaurant full of people. Liam had no answer as to why Mary would refuse him after spending 5 good years together. He was so angry that he went to Mary's home searching for her and so that she could answer the question that has been troubling him.
