Do you think i deserve my partners forgiveness?

I fell inlove with the most amazing guy i had ever met, I met him whilst working in greece, we worked at the same bar, we spent 2 amazing months together and then i left and went back to england, i was lost without him, scared because i had been used to guys in the past cheating on me, i got it into my head that he was just going to do the same, i fell apart and made a mistake myself with an X partner, that one time made me realise even more how much i loved my boyfriend, and i swore to myself never to do it again. I then moved to live with him in spain, 7 months later after having an abortion with my partner i admitted to him the mistake i had made all that time ago, he told me everything was going to be ok and we tried, 2 months later he then left spain to go back to his home town in greece to work and i went bak to england, we had planned that i would go out there to join him, but then he dumped me, says i have ruined everything and that i never loved him, i feel so abondaned and that it was just all broken promises, i dont understand why i dont deserve a second chance after everything, do you think i do? what do you think i should do?
