Sorry for your loss,I lost my wife several years ago just after her 34th birthday.
Wanting to spend more quailty time with my kids we discovered camping.first a tent,then popup,TT, etc.I cherish the time I spent with my kids when they were young.My youngest just graduated high school this year. They still talk about some of our more memorable trips and talk as if it was just yesterday.
Luckily the lord blessed me with a second wife that enjoys rving as much as I do and now I've got grandkids that just cant wait for another trip in papaws bus.
I know its tough but concentrate on the good times you had and the pain and hurt will turn into a cherished memory that will always bring a smile to your face.
