By all means! But what makes it different here is that they’re not two people who have mutually agreed on not marrying. Zoe has made it clear many times throughout her videos that she dreams of getting married and having children, as she’s a very “maternal” person. She has also emphasized more than once that she expects a “ring and a bump” by the time she’s 30 (a wish she’s almost definitely not going to have fulfilled). So it’s not about them not marrying, it’s about him being an asshole who’s leading her on for years constantly being rude and jokey whenever she mentions the topic about which she obviously cares a lot. The best example of this is in a video of them on Alfie’s channel I believe, titled “marriage and children talk” or sth along those lines. She just brushes it off as if it’s not a big deal when you can clearly see it bothers her, she just doesn’t want to put pressure on him.In their defence, I don't get why everyone keeps getting on at them about getting married and having kids. Not everyone gets married
In a nutshell, absolutely nothing wrong with not getting married, the problem arises when one person is looking forward to it very much and the other is an inconsiderate prick.
