Consider these two sentences:
If he asks me I will accept his offer.
and the second one:
If he asked me I would accept his offer.
what is the exact difference between these two sentences?
Referring to my knowledge I think that the only difference is that the first sentence implies it is likely that he asks me but in the second it is unlikely that he asks me. Am I correct?
And my second question:
Is this sentence grammatically correct?
If he asks me I would accept his offer.
If it is correct what is the difference between this sentence and the upper ones?
