Im selfish

My husband has a daughter

He is 38 years old

I am 35 years old

She is 21 years old

TTC and nothing has happen if I become a step grandmother before a mother to my biological child I know I will have a melt down . I feel bad saying that but it is true. My step daughter has a serious BF and I am nervous of her beating me to motherhood

I guess I should not worry there is not anything I can do anyway
