Partner has a female friend from school I’ve met her once on a double date. They meet up maybe once or twice a year if he’s over her way for work. She’s got a baby with her partner and we are due a baby soon. They have arranged to meet up with the baby and she wants to give us some baby bits. He’s not over that way for work but making the 40 minute journey. I have the day of work and would have loved to have come for lunch but he hasn’t invited me. Should he have invited me I respect the fact he has is own friends and meets up with them on his own but this time it’s different he’s meeting the baby having a nice lunch.
