Find someone bright, motivated and ambitious. The rest will follow.
My DH and I have said to each other we’d live in a shed together, because we know that neither of us would allow that situation to continue for very long.
Find someone bright, motivated, ambitious (for the same things as you are - whether that is a home or deisgner clothes) AND has the same financial approach. You don't want to be living in a shed because ONE of you was a spendthrift - that way lies loads of resentment.
Exh ws financially abusive. We had plenty of money between us but he was in control and I wasn't allowed to spend, not even my own money. Enough said.
Then had a fabulous relationship, all the spark and excitement you'd want. He was bright, motivated, ambitious in a respected extremely well-paid career. He was tender, kind, faithfull. And terrible with money. Give him £100 and he'd spend it 3 times over, and not realise, or not recognise what was happening. Despite all the love and compatibility, there was no way I could stay with him.
My now dh (of 30 years) is the steadiest, most principled, most responsible man I know. He is generous but not frivilous. He also understand how my previous financial abuse has left me feeling vulnerable at times. During COVID when my income stopped abruptly he immediately stepped up and covered all of our bills. It feels easy to make shared financial decisions. When my parent died we agreed to give most of the inheritance to our dc. When his parent died we blew most of it on a once-in-a-lifetime holiday.
Financial balance and openess doesn't sound like the most romantic of qualities, but it allows us to engage in the rest of our romantic life from a base of equality and security.
