But does by the end. I see too many of these where the female lead can't choose between the male lead and another guy and then doesn't in the end and that leads to an unresolved romance. I hate unresolved romance. So are there any where she has difficulty choosing at first, but then decides in the end and chooses the male lead? So I want fickle, but then decides who she loves in the end.

These are all shoujo, you didn't say exactly what you were looking for, so not sure if these fit ...
Hirunaka no Ryuusei
Heroine Shikkaku
Ao Haru Ride
Strobe Edge

I find most shoujo resolves in the end.

I would try searching for "Love Triangle" in categories. https://www.mangaupdates.com/series.html?category=Love+Triangle%2Fs

Yeah, I'm looking for ones where she specifically has trouble choosing. The ones you listed, she never really had a problem.

Hirunaka no Ryuusei - She loved one guy and then the other.
Heroine Shikkaku - She loved the main guy.
Ao Haru Ride - She loved the main guy.
Strobe Edge - She loved the main guy.

Stuff like Moe Kare!! where she literally is torn between the 2 brothers.

I just read one of those today!
