One of the myriad of reasons I binned Ex was that we had one telly. Not because I could never watch anything I wanted, more that I have zero interest in watching TV period, so she'd come in slump in front of the TV and refuse to move the rest of the night, whereas I'd be off doing my own thing that didn't involve her or a TV.
It's different with current because we don't live together, so I get plenty of time on my own where I can do whatever I like, so I don't actually mind sitting down with her now and again and watching a movie or something, whereas living with Ex was a case of the bloody thing being on by default, with her slouched on the sofa watching brain dead shite like Strictly/I'm a Celeb/Eastenders. No ta.
