Getting other people's perspectives is fine. However, you need to realize that you have got the right and the ability to decide whether she is someone you would do well to marry. Your conclusions can't be based on "These people convinced me of this, or that." This is your life. Your opinion counts more than a million people saying what they would do, in your shoes. Affirmation and validation can bolster us up, but they can't do our thinking for us.
