I married my husband almost a year ago. Prior to our engagement, when our relationship was first becoming serious, we got a lot of advice from friends, books, and well-meaning strangers regarding how much we should tell each other about our past relationships.
The less they know the better, it’ll just hurt them.
It’s in the past — why drag it back up?
They should know everything. Get it all out in the open.
Talking about your exes will make the other person feel insecure.
Don’t talk about your exes EVER.
Some of that advice is definitely valid — but the reality is that every couple, even every individual, is different.
