What's wrong with this picture
I been dating this woman on and off for about 2yrs, I'm 32 and she's 25.
I have started to notice some interesting patterns. When we're together in public, in social company etc, she's very clingy almost infantile. When ever another woman remotely even looks at me she's all over me like a hawk. Yet this same woman, whenever we're alone is downright hostile(always trying to create contrived conflict). It's literally like being with two completely different people.
We've gone through several breakup-back-together cycles(initiated by her)... It's gotten to the point where, avoidance seems to be the only viable option for me.
Almost from the very beginning of the relationship, I was subjected to these over the top rage tantrums, that involved breaking my personal effects whenever I was not around. Truth being told, at the time I was absolutely shocked(never having experienced such a thing in relationships prior). It initially just assumed it was PMS thing... but after talking with her a bit, I suspected there was much more at play. The net result I tried the patience/support thing.
What going on?
I definitely already know it's not normal nor healthy.
Suggestions please.
