So hear me out..
I love someone but he's so bad for me. It took me a long time to cut the tie but I did and I had a year on my own. Now I've met someone and I’m so happy. He's funny kind, I really like him. Our sex is immense. My feelings for him are different though. I don't doubt them, they're just calmer. Not so intense. Is that normal?
AIBU - not normal, you don't like him
IANBU - different love for different partners is normal, your feelings are real, just different.
