買い物を強要するのはよくない

It is not good to oblidge someone to buy a thing.

I'm not talking about going shopping itself.
It's OK because it can make the relationship keep good way.

However, obligation to buy doesn't make a partner feel happy.
It should be stopped by just suggestion, shouldn't it？

Show me a reason good enough worth buying something if think I really need.

Miserable？

It's no way!!!!!
