Aside from the mushy nonsense like being able to hang out with someone I love every day, there are real, crucial benefits to cohabitation - especially at a time where property has never been more expensive and many young people will struggle to buy a home without doing it with someone else. Plus - not having to do all the washing, cleaning, decorating, furniture building, cooking etc by yourself, surely that's a benefit?
This!
Being happily single is great and society would be enriched if more women felt confident living alone and doing their own thing. But quite often these threads fill with people saying 'I'm happy but if anything happened to my partner I'd stay single as I'd be fine like that.' And it's all this hypothetical thing from people who haven't experienced the reality of it over the longer term.
Yes, being single long term can have massive benefits. Some of the downsides I've experienced include missing someone to make you a cup of coffee after a long week when you're feeling run down, someone taking over the cooking or coming up with a new recipe you wouldn't have thought to look up. Someone to share all the little ups and downs - it gets you down after a while when you've had really great or difficult news and there is no significant other to really share your joy in a way busy friends don't have time for. I have a major life decision to make in the next year and even just having to make that alone and it not affecting a significant other (financially, emotionally) is lonely. Friends aren't really invested even if I could talk it through with them because it's not their life, a partner would be someone to mull it over with properly and be a source of support through the difficult bits of carrying it out.
So yes, I definitely wouldn't settle for a crappy partner and I really mean that, but I also believe a good relationships is preferable to being alone by far.
24 is generally too young to close yourself off to a decent relationship, but do what's right for you OP.
