That's true, some of the neuroses commonly associated with women sure are a frustrating thing to deal with.
I honestly wouldn't give up the pleasure for them though.
You might just need to spend a little more time alone before you miss being loved again.

My resolutions are simple:
1. Go to University and fry your brain with Korean grammar and teachings of Korean history and culture.
2. Don't take shit from nobody
3. Get a camera and a nice purse
4. Get a job and do it good!
5. Stop wasting time on people who're obviously too ignorant to realize that you're not stupid enough to take crap from them

If you give her no reason to be jealous, she'll only act jealous if coming from bad experience with - for example - a cheating previous partner OR if she's used to being left behind by either friends, family or alike.

Personal experience ofc.

Well I don't have a phone. (personal reasons)

Appart from that I don't see any other reasons. Just hormonal dysregulation perhaps.
