spouces death

ive been reading cure zone for a while now and i finally got the nerve to write. my wife passed away almost 2 years ago in my arms from ovarian cancer. i miss her terrible, she was my life, my best friend, my everything and it is hard to pick up where we left off. now having to live without her with our two daughters , 9 and 11 yrs old, it is hard to date. ive tried to date other women and i find myself thinking of her when im with a woman. i pray and read the bible or listen to it in my car from the tapes my friend gave me so i can keep from dwelling on it.am i doing the right thing? theres alot more i could say but i would be up for days writting. its just that my wife was my world and i loved being around her and the kids all the time and now there is a big part of me that feels empty inside. it just feels really weird to not be with her by my side doing things together. thank you for listening,god bless you all, sam
