Disgusted from myself

My ex only used me for sex... I feel played.. I regret... how I can stop feeling like that?

I gave him 2 chances after breaking my heart and he betrayed me.. he was an expert liar.. and now he left me again.

I was so good to him.. now I ONLY feel how much he used me...

Now I understand why after sex he used to leave..

My heart is completely broken.. I can’t express the feeling... I feel regret and worthless. I did everything for him loved him from my heart..

Don’t know how to heal?
