Do I have a right to be annoyed?

So my partner and I are moving into a house together next weekend, (currently live with my mother) and since we got accepted for the house she’s been saying and telling us where our furniture HAS to go.. like today she was like ‘the lounge has to go on that wall’ ‘the bed has to go this way, not your way’

It’s really pissing me off because well it’s my house not hers 🤦🏽‍♀️
