What would you call this type of person / relationship

When where alone in her house if she doesnt get her own way, e.g to spend a certain time of day with me she will continuasly ask to see me although I have good reason not to see her e.g I have to go to bed early for work. If she doesnt get her own way...

she will slagg off my family and also lock me in her house and get really angry with me. Even getting up as close as head on head and swaring and shouting loudly at me.
Pushing me, continuasly tapping of my arm / side to get my ttention when im tired or watching a film and not paying great attention to her.
Swares and carrys on at my mom and family. For example if I want to spend a day out 2 see my auinti who I hardly see my girl friend will get nasty and sware at me and my mom.
When I dont want to come out, she continuasly nocks at the door, bangs on the windows and throws stones at the bed room window to get my attention even if im in bed for work as I work nights.
Always checking my mobile phone to see if im cheeting or have any girl contact.
She will also deleite any girls numbers out of my phone and result in a mood and swares at me and slaggs me down
If I stay with her when I have work she will keep me awake by putting on the tv / flipping a magasie next to me so I canhear pages flip over.

Askes me how much I have in my bank account

Askes me to always lend her money as she doesnt work. When I say I carnt she slaggs me off, says I dont love her ect.

Always says I dont love her or care about her because I dont spend money on her a lot.

Gets in nasty moods because she carnt spend my birthday with me as she doesnt get on with my family. So she wants me to not see my family but see her on my birthday. Becausei want to see family this results in slagging me down and family down making me feel bad.

Grabbing my hand to hit her self with it. Tells me to hit her but I dont.

Threating behaviour towards me if I get mad with her saying nasty comments about my mom and family.

If I dump her she comes around to my house (moms house) and bangs on the door, windows, shouts in the garden, hangs around out side my work, crys says she sorry and wont do it again, and its been happning for a year.

Doesnt like me going to work, always askes me to stay at home.

Says she will hurt her self if I leave her

Picks up knifes when we fall out as if she will hurt me or her self. But puts it down soon after or if I leave the room.

Slaggs me off to my own friends and doesnt let me go out with friends or family. She will do her up most best to follow me if I am with friends. She will test my friends saying im not coming out if they ask. She tells me if I love her I will stay in with her and watch tv and not see mates.

As a result of this I have lost my friends so they hardly bother with me now.

She tells me what times to be ready for. Times to be up for. Times to meet her if im late this results in argument and slagging me down.
Throws my things around, damges my car (am only young and the car cost me a hell of a lot of money) but she slams the door and says its crap and slaggs off my car.

I ask her why wont she leave me if she isnt happy with me, all she says is she loves me and carnt leave me. Which I dont understand, I dont see how she loves me.

She has no friends at all..apart from one lass who is my mate who talks to her. lots of popele slag her off...

Causing problems with my family and me

What is this relationship called ??? What cani dooo ?

Well she sounds like she's crazy and obsessed with you. Maybe she has some mental issues. I don't know what to tell you, maybe you should stop talking to her. Just completely ignore her. She sounds very psychotic. This might be the worse thing to do, or the best thing. Honestly, maybe you should move. lol. Try to runaway from her..

she sounds like one to get away from, FAST.
