Why is it an issue?

It happened in the past, so what is the point in tying to change it? What has happened has happened, he is with you (or whoever it maybe but i don't buy the councellor story)

It is times like this when people reading too much into things will create a rift, and that will keep on growing if the person keeps delving into it. What is in the past should stay in the past, and not be dwelled upon. If they are fantasies then big woop, everyone has them, it's nice to induldge them.

Sounds more like a trust issue on the womans behalf to me.

the difference between lasting or not lasting is LOVE
having love once a week high on drugs living a single life without a care in the world is great but there comes a time when the love is meaningless as you have no love for that person.

coming out of this type of a relationship after several years and finding love can prove disastarous if you are still stuck in the drug culture. when you take that drug your brain will want to simulate the same experience but with your loved one.

as we can see the two do not mix
