I have been with my partner since dc1 was 10 months. We now have two other dc's also. they are all under 5. My partner treats them all equally and loves dc1 like his own despite dc1 having regular contact with his biological father. Because dc1 was so young when we got together he has grown up knowing my partners parents as grandparents. Up until now they have always been treated the same.
Last week my partners father asked for dc2 and dc3 bank a/c numbers to invest some money for them. Both myself and partner hurt and offended that he wants to make a difference between them. We feel different if dc1 a much older child but my partner is raising 3 kids not 2 and we treat them all exactly the same.
We have more or less said its 3 of them or none of them, its so not about the money and would prefer the whole episode hadn't happened because we feel it has made his feelings clear.
Its his money but i feel i would be letting my child down to let this happen. Am i being unreasonable?
