How to budget as a couple? Who pays what?

Hi there,
OK, some of us are or been in LDR, then got married, then moved or planning to move to UK. What do you do with your own property back home? Do rent out, do you sell do you bring money into marriage? What if relationship/marriage doesn't work?
I know it sounds strange, but being older and having bad experience in the past I want to stay independent having my own place and money. I love my husband of almost 4 years and plan to join him in UK within 3 months, but in meantime would like to keep my condo back home and some savings just in case. I am too old and too smart for this saying:"What is yours is mine, what is mine is yours". I worked very hard to have some financial security and I don't want to bring on a silver platter to my husband who is a spender and doesn't think about tomorrow. He made a few mistakes where he blew all his money (not on me) and that why I am very cautious. Moving to UK I want a 50/50 plan and want him to be practical and take responsibilities for budgeting our daily living. It is a very delicate issue, yes we love our spouses, but to avoid future arguments and disappointments (shortage of money in a family is the core of arguments) how to deal with this?
I would like to hear from you, how you deal with money issues where you are a saver and the spouse is a spender.
Am I too selfish, too practical?

Is your spouse fine with you keeping the condo and setting aside money 'just in case'? Hedging your bets may not be the best route where marriage is concerned.

It sounds like you need to have an honest discussion with him and share your concerns about your finances. But if you really don't trust him, why not just have separate accounts?

My husband and I had different perspectives about money, but when we decided to get married we both compromised. We created a budget together and decided on what percent of our income will go to savings. Yes, it took a while and there was some frustration along the way. Then we set up a separate savings account. Each month money is directly transferred from our current account to our savings account. We decided no money from savings would be spent without both parties complete agreement. We also agreed not to spend more than £100 in general on anything without talking to the other person. We didn't prepare anything for if our marriage doesn't work because we are both fully invested in making it work.

All this is just my opinion and I don't know you or your relationship, so feel free to disregard.
