DS (age 10) is taking part in a “sponsored bounce” - his mum and her partner have sponsored him separately and asked if my DP of three years would be willing to as well. DP doesn’t have kids herself and was surprised to be asked. I made it clear it wouldn’t have to be anything other than something perfunctory however she believes a) since we are a couple I should pay the sponsorship on behalf of us both and b) DS is benefitting from have his parents separately sponsoring him anyway so her and his mum’s partner sponsoring him as well would be an advantage other kids don’t have.
I do see her logic, however part of me feels a bit sad - he’s a kid wanting to do something for charity and it’s not like he regularly does sponsored events (the last was two years ago before DP was introduced). It’s not about the cost - if it were me or indeed, his mum’s DP we’d think “bless him” and not give it a second thought.
For context, DP and I live separately and she is only involved in DS’s life in as much as she pops round when they’re around sometimes and we do celebrations, trips to festivals, etc together. I coparent 50% time and don’t lean on her for parental support. She is very much “Dad’s special friend”.
Can any step-parents help me navigate this? Have you encountered similar?
