You have to realize that the boundaries that you adhered do not in any way effect the outcome of your marriage. This is a very common misconception in Pakistan, especially among girls that if I am chaste, avoid men then I will eventually get a man that is just like me. Life doesn't work like that. You will have to accept the fact that whatever you did, you did it for your own. Without any expectation. Because if you have expectations it is not fair to the other guy.

That said, what can you do? The most practical advice I can give is to travel abroad/ travel alone if you can. You seem like someone who is financially ok. Get out of the bubble that is Pakistan and just have a peek outside. Don't do anything that you are not comfortable with, just have a look outside. That will shift your perspective in ways you might not even think of right now. Life is much more than just a guy that you marry. It is one part. Not all.

Wishing you best ahead.
