Opening windows and indoor plants!


I have tried to look for an answer to my question everywhere but I could not find it.
I have quite a few indoor plants stacked on my windowsill as my window is quite big. I also have a few tropical plants like a couple of musas, couple of strelitzia, some calatheas (a bit more hidden though) and others like a fern, some cacti etc.
My boyfriend keeps on pressuring me on opening my window whilst I feel like my plants would suffer from it, especially now that it is winter, so I'd rather open the door of my room and open a window somewhere else... Although he argues the windows are too far to change the air in my room  :/
So my question is would opening the window in this weather affect my plants? I'm sure they'd benefit from air circulation and fresh oxygen... so I do that when it's warmer... But what about when it's this cold outside?

    If the temperatures rises above 10C outside, it will be fine. Below that I would keep the window shut.  Also if it is freezing outside,do not trap the plants between the window and curtains, as it can get very cold.

    I don’t open mine either.

    I open the windows for a while in the mornings in rooms that really need airing even if it's cold out, ie bedroom and bathroom.  I don't have any delicate plants in those rooms though.
