No, like other viewers, she married Nelson, the guy she was singing to in the roadhouse.
She thanked Ernie and called him honey, because his agreeing to take her to the tryouts got her on the team, and she met Nelson.
Gee Woodle, Space Kadoodle!

Don't agree. When she married Nelson she wasn't giving up baseball, just taking a honeymoon. She intended to come back but the war was over and the boys were again taking the field.

You are so right.Her love for baseball was overtaken by a far-fetch dream she probably thought would never come true.

Maybe it was the only time he could get away from his job so they could go on their honeymoon? And it's not like she quit baseball forever (as Dottie did after the season ended). She even stated as she waved from the car as they drove away that she'd be back next season. As much as Marla loved to play, she never dreamed she'd meet a man (any man) and I believe that she loved Nelson way more than she loved baseball (and that says a lot) and I don't believe she regretted for a nano-second giving up baseball for the rest of the season.
EMOTICONS ARE BACK! YAY!

I couldn't understand why Marla and Nelson couldn't wait till the season ended to get married.

Someplace in Colorado.

I don't recall where Marla was from in the movie, but here in the south just about everyone calls people honey.

It makes no sense for Marla to call Ernie "honey".
I know people (many of them waitresses) who call everyone they meet "honey." from a pooper-scooper to the Pope. Marla's father used "honey" as a term of endearment for her - it's not hard to imagine her continuing the custom throughout her adult life!

I also have seen this countless times but hadn't noticed that line, or at least not really thought about it. But you are so right! It makes no sense for Marla to call Ernie "honey" assumedly they haven't seen each other all those years, so how would that be?
Luke this is your father come set the table for dinner.

That's funny - I've seen this film many times, but watching it last night was the first time I noticed that line. She's still married to Nelson (per the conversation with Dottie out on the field earlier) and Nelson is right there with her in the scene, so she's just using "honey" as a general term of endearment. But it is odd she'd be friendly with him, even though he did (reluctantly) change her life; he'd have had to mellow A LOT in his old age for any of them to regard him as someone worth calling "honey."

Someone who was actually watching the movie would have just seen the previous scene in which Dottie asks Marla "How's?" and Marla replies "Nelson? He's
good
!"

When they're in the hall of fame, the older Marla points to a picture of Capadino and says "Capadino look, that's when you changed my life honey." She then hugs him, so while I don't think its implied that they got married, I can definitely think why someone would think that.

Marla married Nelson. Capadino was already married when he was scouting girls for the league. What are you smoking?
