Want to start buying baby things

I'm halfway through my pregnancy. I've been researching and wanting to start buying baby essentials. I don't know if I should wait for my husband or just go ahead tomorrow. He doesn't want me to buy anything yet though he won't go shopping with me either. Ugh. I'm not planning on having a baby shower so there's no point in waiting. I want to go ahead but will feel bad if my husband wants to have this baby shopping experience with me since it's our first baby. It's hard when the man won't give you a clear response. I have ZERO things for the baby and overwhelmed by all the essentials I will need to buy. 😣😢😭
