I was told that when I use "since" I have to use the perfect tense in the main clause for instance
- I haven't visited her since yesterday
Not
- I'm not visiting her since yesterday
Yet I found these examples
- You're looking much better since your operation.
- She doesn't come round to see us so much since her marriage.
- Since last Sunday I can't stop thinking about you.
- Things weren't going so well since Father's illness.
Why are 3, 4, 5 and 6 correct? When I don't have to use perfect in the main clause with "since"?
One person says that this sentence "I'm here since Monday" is wrong that I need perfect. On the other hand, here Andrew accepts present continuous
"since" and the tense in the main clause. What's more here Can I use "since" in past simple sentences?
@Jay says it's wrong if we don't mean "because" but in the previous link, @Andrew accepts present simple and "I didn't see him in Malta since I moved there from Egypt." moved to the present is "I don't see him in Malta since I moved there from Egypt."
