My gf just got a boob job. I thought she looked good before. She’s pissed at me for not telling her how great she looks. Did I screw up by not saying something? Now what?
Your girlfriend sounds extremely insecure. She is looking for validation and attention. Actually, you handled it very well by telling her you thought she looks great either way. Turn it around by telling her that you are happy for her if it makes her happy.
