Am I wrong?

Is anyone going through this? My husband and I agreed back in October to start trying this month until we get pregnant again. We have a 1 year old together. He was an only child as I was the middle child. Me and my sister get along real well Bc we’re close in age. I don’t even think he legitimately cares if he ever has another baby. He says he wants his little girl but that’s it. I’ve always wanted 3-4 kids. He doesn’t mind having just one. Anyways I’m telling him how I’m ready for another one and he’s just like nope I’d rather wait until our son is 3-4 years old. It honestly makes me feel some type of way. I don’t even know how to explain the feeling. Like i had all these plans with how i wanted my children spaced out with his agreement in the beginning and now he’s backing out. I guess I feel so hurt and helpless. I don’t even know what to say to him. It really is hurting our relationship. Any advice?
