I have a few friends that i am sure are the same type. They are such different people individually but show the same pattern of behaviour when things go wrong (and it doesnt even have to be majorly wrong!).
Basically it starts out like this...they get a boyfriend, everything in their life is happy and wonderful. They are way over the top with how they imagine this relationship to be, idealising it and holding it as the biggest romance of the last century. (how could anyone be in love as strongly and passionately as them? is how they see it in their heads.) But the thing is everyone can see their relationship is nothing like that. And it can happen so fast, with almost anyone when its obvious they dont actually click and the relationship is one-sided and all focused on how they feel about it. They dive full course into relationships in a sexual way and tell EVERYONE in detail about it. They claim their boyfriends like territory and tell everyone about it to show others that this man is 'theirs' and how much he loves them etc. The guy soon realises hes been claimed but sticks around a little longer for the sex...which they soon realisecomes with a high cost (non-stop texts, jealous accusations to the point of stalking their boyfriend, clingy behaviour etc).
Then the relationship starts to go sour, they cling to their boyfriend no matter what he does and start to self harm as a tool to try keep him around. They also start coming up with stories about being raped, becoming pregnant or going to hospital etc for various reasons. They starve themselves saying maybe he'll love me if im skinnier or realise how much i miss him and need him. In the end they start acting like those psycho ex-girlfriends you see on movies!!
I believe they are extraverted by just how much they NEED people around them and cry for attention with this behaviour. Does anyone have any idea what type people like this could be?
