Generally speaking it’s better to wait few dates before sharing details.

So I’d advice to avoid talking about past relationships on the first date. People need to know if one has children and was legally married and is divorced or widowed but if you are single it’s fair to assume you had relationships, how and what and when no need to share details on the first date. It’s usually red flag (not over past boyfriends/girlfriends). Better to wait till maybe third date.

Saying all that, there are exceptions. My husband told me on the first date that he had a bad marriage and was abused and other details (all were true). It’s was a bit shocking he shared it but he just felt comfortable and it was ina context of a topic. But generally speaking it’s better to wait few dates

My therapist says that it’s good to be honest but no need to be “open book” all the time especially with people you don’t know

If he asks, you tell him you had several serious relationships in life. That’s all he need to know on The first date
