God is love....

"God is love and if you are full of love you are full of God"....that is the first line on my ex wedding invitation.  Wedding is on Feb 12.   I found myself surprise by the wave of sad that went trough me.  For some reason I feel like he is the one looking good now.  He is even quoting the bible. 
The sadness is still with me.   I don't know how to explain it.  I feel like even tough I am moving on with my life, somehow my scars are still there.  Congrats to him.  To them. 
I love God, but lately have not been to church.   So there, he is the one preaching God.
Am the one trying to live a life with forgiveness, with love;  and my ex is getting the credit.
I am far from perfect.  But I am a loving, caring person.  I don't understand why this is bothering me so much.
My daugther remains cold and warm at times,  since I think the wedding might be affecting her too am just letting her find her answers. 
I will go to a family gathering this afternoon.  Is game night and my soon to be daughter wants me to go and have a good time with her and her friends so we are going.  Hope this feeling fades aways.
Is this normal?
I know I am  a little crazy in the head....but  Is feeling this down when your ex is  getting married normal?   I wonder.
