Gender disappointment

I found out last week I'm having another boy, (I have 1 boy and 1 girl) I love my baby so much, and feel so guilty for feeling like this and I've tried to lie to myself that I'm happy it's a boy. My husband said no more babies after this one so that contributes massively. I feel like I'm mourning the loss of the 2nd daughter that I'm never going to be able to have. I tried shopping for baby boys clothes but I got so sad walking past the girls section. I would feel a lot better about having a boy if we could have more kids in the future bug my husband hit the roof when he found out about a third. I feel so guilty at the same time. 😢
