Am i being mean
So I am 26 and my fiance is 39 he has two children from his first marriage a 10 year old girl and 13 year old boy. Right away i got along great with the kids but than I got pregant things changed a little with the girl being mad and jealous but I kept reasurring her she would still have her daddy ect. Well we had a healthy baby girl and I have become so possesive of her. I dont know if it is just my instincts to protect her bc the 10 year girl still says things like she isnt allowed to do the sports she does ect. The 10 year old gets really angry if i buy my baby anything just lots of jealousy so I dont like it when she is all nice and playful with my daughter like she is a doll. The 13 year old boy is always nice so I never have a problem with him. Is it just my mothers instint to protect my baby the reason I dont like the girl to play with my daughter. I want to be a good mom and stepmom
