Best thing you can do is keep yourself busy with friends, activities, family, and maybe even work.
My wife and I separated last August and it's been very lonely for me.
I have had lots of issues in my own life to work on, and it would have been easier with someone by my side...but I did it anyway because of my daughter.

Good luck and never give up hope...the right match for you IS out there, and you gotta be out there to be found!
