Does she get over stuff really quickly too, like within 5-20 minutes as if nothing happened?
If so, then I've been there. The sex was great, I'd come home and hands probably went straight down my pants, but that few percent of the time she would be mad/jealous over bullshyt that just made no sense. Not only would she get mad, but she would yell even at 11:30 at night when I was trying to sleep, I felt I did just about everything possible for her but when she was mad basically I was a huge dick. In the long run I miss the good times because she was funny and we made each other laugh, but that little insanity was too over the top for me to handle. She didn't take 30 minutes to get "in the mood" which was awesome, and we had a lot of fun but the rest just killed it.
this sounds like her exactly. She does cool off after about 20 min to an hour, and then everything is freaking great, and mostly because I assert myself but acknowledge her feelings as well (which is good for crazies and not-so-crazies). But sometimes she just throws me curve balls and I have such a hard time keeping up. That 90% is amazing though, she's fun and funny, she's sweet and caring, she's crazy sexy and does things and wants stuff that I didn't know could fit into one woman's sexuality. But that 10% is so indescribably unbearable and unpredictable.
The latest crazy: She had made plans to miss a couple days of work and to spend the weekend with me. Suddenly she couldn't take off anymore, and she would even be working later that current day so that we wouldn't get to see each other at all. I say that I'll come see her for the night anyway, and we'll just have a good night on the town. I pick her up, and she says with no consideration of my emotions, "I'm moving to Columbia! Also, I got the day off, so let's go to your house for the weekend!"
Ok, I'm thinking, booty call time. She's pulling the whole "let's do it but then I have to leave for Europe because I'm a secret agent" routine. I'm perfectly ok with this, but I call her on it. I have a private argument with my penis, I reluctantly win this argument, and say that her story sounds suspicous and I want her to be honest with me: if she wants to just fool around then let's fool around, but tell me. We spend an hour about how I think she's a lieing whore, which is understandable, but once I deescalate the situation we go to my place and have a freaking amazing night. And most of the sexual stuff was geared toward me, so I don't feel like she was trying to just get in some booty time.
The night ends and she's absolutely in love with me again, can't live without me, I'm the best boyfriend in the world and she will never let me go. So what the hell is going on?
