How about
I love you and not speaking to you is breaking my heart.
or
Having you as my father was one of the highlights of my life. Being without you is almost unbearable.
or
I want you to know I will always love you.
or
I just want to thank you for all the years of happiness and security your fatherly love gave me.
or
Knowing you loved me was one of the most important things in my life. Now I'm not sure and it's breaking my heart
or
Please give me some indication that you really did love me all those years, and that it wasn't just an act you can switch on an off.
or
Loving you is not something I can just switch off.
or
Your love was one of the few things in this life I thought I could depend on.
