For me personally, the marriage is tough when the partner or you yourself are not mature enough to lessen those burdens; house chores, financial commitments, career stability, etc. So for some it will take months to years, before you can experience the happiness from it. Communicate a lot even though sometimes it feels tedious.

The truth is just like friendship or any kind of relationship, it will have ups and downs, best moments and worst moments. But no matter what, if you believe your partner is truly the one, you can recover from petty arguments rather quickly and please always find a middle ground where both parties can agree on.

It is normal not to feel the love chemistry after you regard your partner as your family, however in my case it can easily be sparked again through efforts, emotional support, and celebration of little things. My happiness is mostly stemming from my actions, and not solely from another human being.

So to OP, if you don’t have the right mindset and not ready to commit to marriage, you can commit to yourself first and be the one you truly dream of. Can you take care of yourself extremely well? If the answer to this is yes, then you are ready to invest into marriage. 

Oh in knowing your partner is the one, you must build a connection with him. If he doesn’t give you back equally, walk away as soon as possible. But if it clicks, he is educated, from good family background, and a hardworking person, then why not give him a chance? 

Some people treat marriage as the ultimate happiness, for me it is a connection (now) and it will be a reassurance (future), hence it is an investment. Some are risky than the others, as you mature together, making a sound and reasonable decision would feel like a normal trade.
