I'm Male. I'm a member for a long-time as MNHQ will no doubt clarify if asked.
DW has been in my life for over 20 years, DSS is 22 and has been in my life since just before he was 2. DD is 19. Over Christmas (DSS not present as lives many miles away) DW told myself and DD her conception date for D(S)S was her birthday - a non-special date in the year (eg: DDs was my birthday over the Christmas period). Over our lives together this has never come to light, and I'm pretty upset as a result. Her ex was very violent and alcoholic during their relationship, no part of their sons' life since 18 months, and apart from a handful of months when DSS was 14 (during which he sought to split us up, acknowledged by social worker who ended contact after school expressed concerns) no contact.
DSS has been raised as my DS, and seen me as such from incredibly young age both in wordage and behaviour, mirroring his sisters' behaviour. Should note he was never encouraged in any way to do so.
So, am I being unreasonable in being upset? Or should DW have been more reserved after so long? Not sure how I'm going to, or supposed to, feel when her birthday rolls around each year.
