Confused.com help?

I’ve been with my current so for 9 years but i still can’t help thinking about this one lad i use to be head over heels for years ago (not in love) like what could have been, we stopped talking about 4 years ago but sometimes I miss us just talking he was a really good friend and was always there for me like my so sometimes just can’t be there for me.

Am I awful for missing someone I know I shouldn’t be missing? I don’t want to be with this person because

I do love my oh just sometimes I wish I had someone emotionally their for me.
