Shaadi, or for that matter, any relationship (blood or non-blood) is some sort of compromise. Never forget this and your life would be bliss...
At some point in life, we do compromise with our parents, our kids to keep life going then why can’t we do that with our spouse. Its perfectly normal I guess. No two individuals can live together in perfect harmony all the time. If they do, both or one of them is not normal.
I'm failing to recall a pretty similar comment by Brook Shields who is an accomplished model and juggled her life between marriage, career and motherhood. BUt the jest was pretty much the same what I have pointed as to why do we expect marriage to emerge as a perfect relation when our other relations even the blood ones are never perfect. More so, in a marriage the two people are new to each other, different personalities as compared to our blood relations.
Marrying or not marrying is upto you , your choice (well, I admit not so much in Indian context) but let me tell you I have seen people who choose not to marry and then few years down the lane they feel left out as all their friends are married and settled. And I have seen them going through a lot during that phase which is kind of ugly.
Anyway, trust me shaadi is not as bad. But If you are aiming for a perfect marriage (regardless of love/arranged) that doesn’t exist …not feasible …Period!
