"since then" what dose it mean? ?

Question

since then = ever since

Answer 2

mean when it happened a long time ago, till now

Answer 3

These examples should clarify your doubts:

>>He broke his leg on 8 Aug this year when doing silly bicycle stunts to show off to a pretty school mate.

     Since then, he has not dared to go near any two-wheeler or pretty

      girl.

>>She was molested during a party at a chalet when she was 14. Since then she has not attended any party away from home.

Just using 'since then' is sufficient rather than saying 'ever since then' which is too wordy.
