My husband is a bit like this. He might suggest places to eat, but never holidays or things. Sometimes his apparent inability to make decisions does drive me a bit mad, so I do get where you are coming from.
I think, in my husband's case, there are three driving factors here. The modelling he had at home about who makes all the decisions is one. We talked and he is also very insecure about making decisions in case he gets it wrong. For example, he gets really anxious about choosing movies to watch in case it turns out to be a bad one. I told him that if it turned out to be a bad one, we just laugh about how it was a really bad movie and does it matter? If I chose a movie and it was bad, did he think badly of me? If the restaurant is bad, same thing. We laugh about how awful it was and go somewhere else next time. He felt more reassured after this discussion. Is your husband an anxious person? Also, we have different strengths and weaknesses. My husband finds it hard to be organised while I am naturally very organised. I think this is similar at home and my natural ability to organise is easier for him. Do you relate to any of this?
If you can find out where your husband is coming from with this, maybe you can find a way to work with it.
