Hello, I totally understand your confusion, marriage is the most beautiful but still the most difficult decision to make in our life. You need to be completely sure about the person you are marrying. And once you decide about it stick to the decision you have made and stand by it. I can give you a small trick take a note book make two columns and in one side write down all the good things in your relationship and the other side not so good parts of it. Compare it and the answer is more clear . It's more difficult to solve things in your head alone and more easier when you see the differences in front of your eyes. And let me tell you one simple thing about life, no relationship is perfect at the start you can make it perfect with lots of love.
