She constantly wants to break up and uses her ex as excuse..

[geartips4]

Hello to all
I will try to make this short
4 months ago i found a girl which i liked a lot, and we basically fell in love on first sight..She had a boyfriend then, but she immediately told me that she is not happy with him over the years and that instantly when she saw me she wants to break wit him because she really likes me...20 days passed and she broke with him...We hooked up and so on... She was with him for 5 years but they broke few times and then got back together etc..
I talked with her about it and she told me that she never loved him but he was only habit because of so many years behind them.so this was relief to her.

When months passed by i saw that she has nasty habit that when she is hurt or something in our relationship she wants to threaten me how her ex bf loved her more then i love her how he was nicer how he was more supportive and so on..and she is doing this often.. today we had a argument, because i told her i don't want to hear her talk about her exes and how many times she slept with them etc and she told me ok, but again this night she did it...

I was angry and i didn't want to talk with her and told her that she did it again and i don't know what to do..she was panicking and she called her ex BF on phone and on Viber to ask and complain how she is not felling well in relationship and how i am bad with her...

I immediately left her and she claims now that it is my fault blah blah.. I really don't like this because i don't trust her, because in future she may break with me and cheat on me or call her exes if she is drunk etc..that is why i don't know how to cope with this feeling.
What do you think i should do and how should i react?

THis is only sufrace, she always threatens how she will hurt herself because she is madly in love with me, and how her ex bf loved her more then i do so she thinks destiny is maybe with him although she doesn't love him at all and she says she will do that only to hurt me and be hurt forever...

I think she lied to you about not loving her ex boyfriend. The fact is that, it's impossible to be with someone for 5 years and not love them. If she keeps talking about her ex, then she's obviously missing him and probably wants to be with him. Also, she told you that her ex loved her more than you, this implies she might be considering going back to him.

If she broke up with her ex just after 20 days of meeting you, then you are probably in a rebound relationship with her. She wasn't over her ex before entering a relationship with you, so your relationship with her is rebound. Obviously, she now wants her ex back hence she called him to tell him she's being badly treated by you. It's best to leave her before she leaves you.
