How did you feel about the loss? What type of loss was it? These variables can answer your own question. You can love someone and not be in love with them. You can be "in love" with the person as well. There is also the feeling of missing a person in your life. You are best to judge where you stand here
I don't know if you refer to a broken love affair or a death of someone close but I had a buddy. His name was Bill Hiller. I met him in 1974, at Grumman Aerospace. I was in Structural Design, he was in Aerodynamics. We, as a group, started going out to restaurants, etc. Eventually, card games, rifle, pistol shooting then camping and hunting. I introduced him to the girl he later married. I have the greatest respect for him, his mom, dad and his brothers. Well, Bill passed away about 3 years ago. I miss him very much. He was a great friend, fellow shooter and drinking buddy. I always say that when I die I want to run into Bill as soon as possible. He was a great friend.
