The Marriage Checklist - for anyone who isn't married yet:

Do not marry unless:

1. You understand the risks of marriage: research no-fault divorce, family law in your locale, divorce statistics in your demographic, etc.
2. You have accepted responsibility for your life, you work hard to improve yourself, you love yourself first.
3. You have a sturdy identity: you know what you’re good at, you know how to get paid for it, you have confidence in yourself, you are an adult. Additionally, your SO has a sturdy identity
4. You have a strong financial footing: if you don’t, start now. Go to /r/PersonalFinance, lurk, branch out, start saving money. Having money saved up will force you to research what to do with it.
5. You trust your SO as a mother / father: they have sound decision-making skills, can be trusted with real responsibility, and will make a complimentary contribution to the partnership.
6. You have amazingly few personal problems with each other. Obviously this is hard to quantify; but the better your relationship is at the outset, the more room you will have to absorb unforeseen differences and conflicts.
7. Your purpose for marrying is to accomplish something larger than yourselves, such as starting a business or raising a family. Otherwise, divorce is too pricey a risk and any other activities can be enjoyed without merging finances.
8. You have enough mental and emotional space to make this decision for yourself: you are not being pressured by outside forces such as your SO, your family, etc. If you are, you have to work to cancel out those voices.
9. You are attracted to your SO and the sex is great. Related: you are prepared to never sleep with anyone else besides him / her, ever again.
10. You love your SO. If you have any doubt about it, the underlying reasons for your doubt will eventually turn from small fissures into large cracks.
