We've had fights before but this was probably the most serious. I ignored her for a full day over something that wasn't looking back, that serious. We've talked about it but she said things like "it was petty, immature, didn't know you were like this." I've since apologized and she accepted it but ever since then the chemistry hasn't been the same. I asked her jokingly to come over and she said "not today" and then she said she wasn't horny when I was. Good morning texts are brief, etc. She's not mean or anything but it's obvious she's not fully over the fight. It's only been a day since I apologized. What should I do?
