How could I restart again and forget him?

I was in a 7 year relationship

He cheated on me and left me for another girl on our wedding day

It was two years ago and yet i couldnt move on.. i still love him still cry like it happened yesterday

I left my work.. stayed at home for long time

I feel like i am a loser.. a very weak woman

I feel a ashamed

Please help me
