Marriage is like gardening. Every morning, you get up and start working. So, the first advice i want to give is that you have to DECIDE to invest in a life with someone else. Too many of us focus on what we will *get* from a partner or marriage. Focus also on what value you will add to the life of another person, and get ready to put in the hard work. Whether you are a man or a woman, learning to give love is as important as learning to receive love with a sense of gratitude.
Two generations ago, marriages were done like contracts. Both families decided on many factors and then the bride and groom got involved. We still need to navigate those factors, but by ourselves now.
This is my suggestion:
A. Values - list what your values are, and choose someone where there is values alignment.
B. Pay attention to the family - When they meet, do they respect each other? Do you find genuine affection in their conduct towards each other? Irrespective of what you are seeing right now in your prospective partner, the ONLY behaviour pattern he really knows is the one he has seen and done in the house. So, if the two parents are not listening to each other, if one of them is doing all the talking and the other is doing all the nodding, rest assured that your life will look a lot like that too. Some people are ok with that, some are not. You can decide.
C. Finance and Moneys - Have an open chat about wealth creation, contribution to expenses, contribution to respective parents. Discuss any pending and upcoming loans, family liabilities, financial responsibilities (like if you have a younger sibling whom you have to settle, tell them upfront), etc.
D. Children and Caregiving - How many children and when. It is perfectly fine for the mother to be the primary caregiver to kids or elderly parents, but at that time, the financial burden needs to shift completely to the other partner. Likewise if the father decides he cannot handle workplace stress and wants to take a break. The financial burden shifts completely to the mother and the caregiving responsibilities go completely to the father. Best to have this discussion before you get married.
E. Dietary and Cultural Practices - Small but important changes in our diet and culture is like carrying a glass of water - for 40 years. Figure out if something is a dealbreaker for you and stay true to it.
F. Expectations from a partner - Ask your partner what role they want you to play in their life, and tell them what you would like too. If TLC is important to you and your partner believes that actions speak louder than words, that is going to be difficult. Likewise, if your partner expects support irrespective of life events, and you just cannot handle, say, the loss of a job, then its not the right fit. In one marriage, the husband said he just could not deal with a fat wife, even if the fatness was a result of bearing his child!!
One question i often get is around chemistry and physical attraction. What i have observed is, that we start to find people we love physically attractive. So unless something is absolutely abhorrent to you, you can safely ignore this. The most smouldering chemistry succumbs to the first emotional manipulation. Some great lovemaking starts with a caring embrace. Unlike dating, where physical chemistry matters A LOT, in marriage, its not as important. We change physically and so does our partner.
Treat it like you would treat a job search.
Put "About Us" first (What you bring to the table)
Then the JD (expectations)
Then do the selection procedure.
Then, commit to the relationship and give it your best shot.
Sorry, very logical and left brained answer.
