Simple Present Vs Present Perfect Continuous

[ravikumarkargam]

Here is the sentence used by an English teacher in youtube's videos.
"I find it awkward working with Peter ever since I turned him down for a date."
Here, simple present is used instead of present perfect continuous.
When should I go for simple present instead of present perfect continuous?

Thanks,

(Today) I find it awkward working with Peter ever since I turned him down for a date (last week.)

you could also say:
"I am finding it awkward working with Peter ever since I turned him down for a date."

The verb tense is written how you feel presently, based on what happened in the past.

I feel present continuous you have used is addressing only the present situation.
Is it also talking about how you feel in the complete period after the incident happened?

Can I use,"I have been finding it awkward working with Peter ever since I turned him down for a date"?

Thanks,

"I am finding it awkward working with Peter ever since I turned him down for a date."

The 'ever since' makes the tense in this sentence incorrect.
Compare:
"I am finding it awkward working with Peter because i once turned him down for a date."
The meaning of the tense is that I am currently working with Peter and find it awkward.

"I have been finding it awkward working with Peter ever since I turned him down for a date"

I was working with Peter at the time he asked me to go out on a date. I declined; and ever since, I have been feeling uncomfortable/awkward working with him. (Peter and I are still working together.)
