Been seeing a girl for over a week now. We've been frequently meeting, staying over at both my place and hers. Things have mostly been very good between us - great sex, great chemistry, great intimacy and affection, great conversation etc.

I spent all day with her yesterday (mistake) for the first time, and things were smooth sailing as usual, but then in the evening she started to become very playful and manic almost. I don't mind the playfulness, as I can be playful back, but she was becoming a bit too much in other ways, for example:

She kept calling me gay this, gay that. I was just ignoring it mostly, or teased her back. I'm no stranger to shit tests or joking around at someone's expense, but she kept doing it and doing it to the point it was getting seriously tedious.

Another thing was that she then started implying I was some sort of a bitch saying, "she fucks me" (she doesn't) because I like it when she gets on top and rides now and again, and then the final straw was her getting out a vibrator and trying to rub it against my nipple not realising that at that point I was already checked out mentally. I put up with this for over an hour, and then decided I had enough of this attempted emasculation bullshit and left.

Before I did, I told her straight up that she was being a bit too hyper and annoying and that I was leaving. She said, "well this is part of who I am, if you don't like it then go". So I did.

This girl is 1000% into me, and I do like her too for the most part - everything else was cool, but it was almost as though she was a completely different person last night. She went from being this sweet, affectionate and compliant girl I'd been experiencing all week, to some bipolar/hyper aggressive girl all of a sudden. It was strange, it felt like she was actively trying to push me away.

For context: I'm 37 male, she's 28 female. She has been consistently obsessed and devoted to me the entire time we've been seeing eachother. I'm not saying she lost any interest last night, but her weird fucking behaviour put me right off, and me leaving has made her defensive and stubborn. I doubt I'll hear from her, and she won't be hearing from me.

I'm just wondering if anyone could tell me wtf this sudden behaviour is lmao. I haven't messaged her since. I didn't get angry or defensive, I just simply said "You're being a bit too much, and I'm going", she seemed defensive and tried to act indifferent, and that's the last time we spoke.
