Fear, can't trust anybody

Hi,

I am very lonely and depressed.
I can not keep relationskips. I can fall in love with men. I can create deep relationship with women and adore them very quickly.
However, I lasts just for a few weeks or months.
When they do something not perfect it affects our relationship tremendously. They may be i.perfect anywhere in their life, I tolerate everybody, even murderers.
But if they say or do something that sounds not caring for me, I get strong fear and escape from relationship. I can't open my heart to these people anymore. I miss them, I feel sorrow, depression, but can't stay in relationships wven if they regret and offer to resolve problems between us. I just escape with a deep depression. Because I am afraid of abandonment and betrayal so much.
I experienced very little love from my parents.
Please, give me advices...
