James Conway confessed sexual abuse cases to police after his wife saw a Facebook message about him.
At Ipswich Crown Court last Thursday, Conway, 42, of Rougham, admitted five offences of indecently assaulting a girl under 16 between 1996 and 2001.
Catherine Bradshaw, prosecuting, said Conway had indecently touched the girl on a number of occasions.
Appearing for Conway, Ian James said his client had become aware of the seriousness of what he had done when his wife confronted him.
Sentencing him, Judge David Goodin told Conway: “These are grave offences. Offences of this kind are only achieved by a form of coercion and bullying.”
Conway was given a 39 month community order with a requirement to participate in a sex offenders’ treatment programme.
In addition, Judge Goodin ordered Conway to sign the sexual offences register for five years.
