I did not see his selfishness and emotional immaturity until he ran into an old g/f from 23 years ago. He struggled with why he was having feelings for her if he was in love with me, not to mention she lives 400 miles away. After 2 weeks of struggling emotionally with his decision, he decided he had to follow his heart where his ex g/f was concerned or he would hate himself. He completely ignored the relationship he was in, the level of comfort his son came to depend on with me, the support & stability that we had, and the open and honest communication that we shared...all for an old g/f who lives 400 miles away and that he has not seen in 23 years.
