Don't know about the cold thing but very cautious and didn't get married for 35 years after my divorce as I swore I'd never get divorced again even if it meant not getting married. I was hurt and felt like a failure. I needed time to mature and get myself together so I am one who can now say that -
I have equally enjoyed my married time as I have my single time, both have advantages and disadvantages. I think we just need to learn to be happy with whatever place we find ourselves = single or in a partnership.
My main problem wasn't so much with people or men but my own relationship with God as I found life doesn't go so well without having God in your life, even if there are challenges that you have to face as it isn't all smooth sailing even when God is in your life, however, with God in your life you know you can trust in Him to help you get through those difficult times.
So please learn this lesson faster than I did in the above paragraph as it will save you a lot of heartache.
