I feel really bad now, I often reminisce and never thought twice about it, as long as it was nothing that could possibly hurt DBH. I talk about old homes and places I visited, places we went to, after all, it's my past and I am also interested in his past, why would I not talk about it? Maybe we both just feel secure enough not to worry. I would hate to have to be scared about what I could talk about. Your OH isn't comparing you, I bet, no more than I am comparing my two husbands. This one is far, far nicer than the last one. But I did go to some of the same places, and it was the places I enjoyed and not the company. Not often, anyway. I had good times but really should never have married Ex.
Having had a child by each has helped in a way, because of course DS often wants to know about DD's previous life. We were away last week in my home county and he wanted to see a couple of the houses we had lived in in our past life!
