So I'm going to be out of town this weekend, and I knew I wouldn't be around for Valentine's Day. Because of that, today I was feeling especially beta and decided it would be meaningful if I went and got my LTR (yes, I have an LTR, yes she's high quality, easy 9/10) flowers and vanilla ice cream, since that's her favorite. I got the shit and headed over to her place. She seemed really happy and I thought it went surprisingly well, we had some fun but I wasn't in the mood for sex and decided to let her marinate while I'm gone. I leave, then about an hour later, I realize she never actually thanked me for what I got her. She coincidently started texting me shortly after about something off-topic and I brought it up. The whole conversation she was acting a lot bitchier than usual. I decided to put her in her place, and of course she was all apologetic after I put on the pants, but it still bothered me. Do all girls get like this, should I even get women anything for holidays, birthdays etc?
