’ve been with my partner for 4 years. He has a child and so do I both from previous relationships. His brother is getting married and myself, my partner and his child are invited but my child isn’t. We have met plenty of times, gone on holidays together and always felt accepted by all his family so this has come as a bit of a shock. There are lots of other children attending the wedding. Would anyone else be annoyed by this, or am I overthinking it?
