The last person I liked, had same issue, she shared one thing her mother told her "..... , you grew up with so many options, that is why now you always keep on thinking that you will have a better option and you cannot commit". I am not judging anyone here, just throwing it out there.
That makes sense. I've never been able to decide. I buy 3 copies of the same book with different covers sometimes because I don't know which is my favourite lol
