Arrange Marriage - Not very sure

Hi folks

Hope you guys have a great weekend...

I need some advice.

Currently I'm going through an arranged marriage set up. I met the girl and we are talking on the phone. Families are very happy and look forward to marriage.

But somewhere I am having second thoughts.

I like the girl. She is not very pretty neither I am, so not an issue. I like the way she talks or she carries herself. I liked her persona to be honest. But at the same time, I feel that spark missing sometimes from my end (I don't know how to put this feeling in word, hope you guys can resonate and understand).

We have an age gap of 6 years. I am not into long talks daily, but she wants the same. I like to have my space, my silence but I don't know how to navigate through these feelings plus her expectations. She seems not very ambitious but content with life. We are opposite in many ways except our music tastes.

I am feeling confused, whether to proceed or not. Let me know your thoughts.
