As NotSpagetti and others have said it is more likely that your adult children just wanted a night out together at the pub. All pretty normal stuff. There are lots of conversations, stories, jokes that they really don't want to tell in front of their Mum. Having Mum present does change the tone of the evening.
Also, I don't think many adult children really understand that a parent, especially one on their own, may sometimes feel a bit left out in situations like this. The bittersweet process of letting go of your children into the world is not a life experience they have had to face at this stage of their lives.
Instead of the feelings of low self esteem you should give yourself credit for having brought up children who are friends, like each other's company and want to have a night out with their siblings. That's a parenting job well done. ?
