"if" in the following sentence
hi there.
I wonder if it’s just my bad choices in men.
 I don't know whether  "if"  has made a conditional sentence in context or not.
"I wonder if" doesn't make sense to me can anyone explain it to me?

Answer

When you say "I don't know if..." there is an implied "or if not."  In this case, the sentence means "I don't know if [the reason for my problem is] my bad choices in men, [or if the reason for my problem is something different]."

A simpler example:
"I don't know if I'll go to the party" = "I don't know if I'll go to the party or if I won't go to the party."
