annoyed he wants me to do it for his kids

So my husband caught me doing my little project and he was excited he even helped me with the signs and took me to take pics picking out spots he thought u ladies might like after we were done he says I think that's kinda cool ppl sending pics from all over but instead of u doing it for me u should've done it for my girls and they could've put from daddy so I could send it to them as a surprise 💔 what do u ladies think? I love my stepdaughters but this project was my gift to him and he wants me to do the work for him & not get any credit?!? Am I being selfish?
