Does it change if men are in relationships?
When you cohabit with anyone (partner, friends, children), you have to compromise. However, if taste and style in decor are very important to you, then if you have v different tastes, it may be hard to find a compromise you both feel comfortable with.
But, as others have said, you seem to be approaching a relationship like going shopping, with a checklist of what you need long-term. IMHO, this means you’re setting yourself up to fail. Imagine if you met a new friend (e.g. at work) and immediately started to decide what kind of friend they’d be in 5, 10 or 20 years when you needed a lot of support. Rather than enjoying their company in the here and now and allowing the friendship to develop organically and see what happens.
Life is so wonderful because people come in and out of it. Some stick around for years, others are more fleeting and you never see them again. You can’t predict which will be which. But they all add to make life a richer experience and you carry this with you.
You can’t control and plan for how relationships will be. They’re not a work project. That’s the magic. I always think of life as a long trek, through various landscapes (mountains, wood, valleys, plains). People join you on the road. Some just for an hour or day, some for years. Some in good times, some in bad. But they all make the journey richer and more interesting. Some people might walk the whole journey with you and still be there when you leave, but sometimes that can mean you get confined to them and miss out on the company of others.
So, IMHO you should enjoy dates and see what happens. Sure, you need certain red lines for your own self-respect. People who show signs of being abusive, disrespectful or controlling are best left at the crossroads. But, other than that, the magic and beauty of life is seeing where it takes you - and who you meet along the way.
Character and values are more important than tastes in someone you walk with for a while. Believe me, when a baby is crying at 3.30am, perfectly aligned tastes in scatter cushions won’t matter a jot. It’s the man who gets out of bed, brings the baby to you to be breastfed and fetches you a cup of tea, all with kindness and humour. A stylish backpack counts for nothing when you’re lost in the woods in the rain.
