I would like to know will I ever get married again? Or be in another relationship again?

Hi mr 95020,
It's difficult to give a difinative answer to that question I'm afraid.
Only you can decide on something a serious as marriage.

As for relationship, I believe that there is someone 'out there' for everyone. Sometimes they are only in your life for a short time and then someone else comes along when you are ready.
Don't despair!
Have fun being single, enjoy the experiences that it offers you and you will be a better person when the time comes for a commitment again.
Good luck!
