She’s acting cold I don’t know why

I don’t get why my girlfriend is giving me the cold shoulder. We’ve been doing so well the past few days then she suddenly gave me one-word replies. I don’t know what I did although I have a hunch. I may have slipped a comment about how hot her brother’s girlfriend was. The said girlfriend was from a foreign dating event and when she showed me a photo I said she looked hot. I already apologized but to know avail. I also asked her what was wrong and she said nothing was but everything just feels so wrong. I don’t think I deserve to be treated coldly if I didn’t do anything wrong.

You called another girl hot. Of course your GF is miffed. Apologize. Send your GF flowers & assure her that she's the hottest girl you know. Then never comment about another woman's looks again.

You need to actually TALK to her in person and have a conversation about it. Texting is a poor way to communicate to your so.

oops. yeah thats pretty bad lol
