Which sentences are correct? (tense)

A. When I messaged my boyfriend, he seems to have been with a girl.

B. My boyfriend seems to have been with a girl when I messaged him.

C. When I was in my car, he can't have seen me.

D. He can't have seen me when I was in my car.

Which ones are correct English, given A,B,C,D?

I think that only B and D are correct English because in sentences B and D, "when I messaged him" and "when I was in the car" belong to "to have been with a girl" and "seen me".

But I think that A and C are wrong because the tenses of when I messaged him" and "when I was in the car" don't match up with "seems" and "can't".

Thank you very much
