love problem...can´t find solution...

I was just wondering if anyone out here can think about Flower essence, helpful in my situation.
Personally I don´t know much about Bach remedies, but looking forward to learn more about this topic. I´ll try to explain my problem.
It might seems banal, but I can´t help myself,even if I´m trying really hard.
For the most time of my life I was happy with myself, I feel good about myself .
Problems starts, when my partner had left me, in the most unexeptable moment, when I was really happy with him, loving him and being loved by him (that´s what I thought).
It reject me really strong...
I was trying to understand situation, and in the same time i started to blame myself as a guilty of it .He left me for his ex-girlfriend. I was killing myself with thinking ,if I would do things difrently, if I would say different things, etc. he would left me... It was 3 years ago, really longs years, and I still can´t get over it.
It still in my life, I´m not the same person anymore. I have problem with building a new relationship.First I keep people on distance, of someone is interesting with me, it´s seems like something suspicious to me...Like it´s impossible like someone can think about me as a interesting person. Later on when I´ll go thru this stage, I´m putting all my emotion in to this person, first distance and than in the very short time-sea of love...Mans are scared of it.
My problem is, I don´t consider myself as a valuable person, I´m getting scared if someone will have a chance to let me know better, then will discover I´m not so interesting, intelligent etc. Once when someone likes me I´m bugging for love, I´m doing all what I can think of, to make this person love me... I´m trying conform him, doing all what I can for him.
I´m sorry if I´m not writing clearly.It´s really difficult to me.
So my question is,how I can love myself so than I can believe that I deserve to be loved?
Is it possible that flower essence might help me? I know my problem, but I don´t know how to solve it...
Thank you for your help. I really appreciate it.
