@Able2KnowOrgTA,
"I have the best, most loving GF in the world except ...."
If you can't get past that exception, we're going to be reading, "I
USED to have the best, most loving girlfriend in the world but I let my own suspicious jealousy ruin it ...."
Maybe she didn't tell you because she knew your own exception is you're an immature worrier who lets his mind run away with him.
If it ain't broke, don't fix it.
