Another one I remembered.....my brother.
My brother, "J" was dating "S" and this was his first real, serious, committed relationship. She was about 3 years older than him and this was not her first real, serious committed relationship. He was about 20 or 21 at the time. Her frustration was growing with his immaturity and lack of relationship skills (e.g. she would come over to watch him play video games with his roommate). S broke up with him and told him that it just wasn't working out. J was devastated.
Lucky for him, his roommate had been there done that and advised J to play it cool and not react. He told him to respect her decision and if he runs into S, to play it as if life is good and he is unaffected. I don't remember the specifics here but if i recall, S went on dates with other men. She stayed in limited contact (LC) with J and was trying to be friends although J had no interest in friendship. He just was polite and stuck to the plan. J had a vacation for a few weeks in Europe coming up. In one of the conversations, J shared this with S.
The DAY that J got home from his trip, S called him. She wanted to meet as she wanted to talk to him about some things. She related that she realized that the pros in J outweighed the cons as well as against the people she had recently gone on dates with - and they reconciled.
They have been married ever since and have two children. One that is going to be a Sr. in High School next year and another that will be in 8th grade. They are a tight knit family.
