The line between friendship and relationship was blurred one wanted more the other did not feel the same. As time pasted life set them apart one got married and the other responsible trying to become established.
They talk but things will never be the same while things felt like an old routine. Why go back to a failed outcome expecting things to change. He was single and she was married he denied his feelings while she poured out here. This was wrong and he knew so he would cut all ties from friends to strangers. She had more going on and he was doing his own thing. She told him he was the one who got away but that is impossible because she got married. Her husband was not fond of the friendship but it was a spike that caused a mild wedge. He didn't want to ruin things so he went away. She would call and text but he ignored her. She didn't like it and knew he did not belong because her marriage was more important.
