She says I'm amazing but she has stuff to "sort out". What?

I'm 29, met a girl 34, about 1 month ago.
Went out 4/5 times in person & talked every day for last 2 weeks.
Danced, laughed, talked. Personalities almost 100% match.
She's traditional & I'm happy to go slow.
We've held hands, walked romantically along the beach, hugged etc.

She's opened up to me about family, life, almost everything. (Except past relationships)
Told her mum "mum I met a guy", her boss & some friends about me too.
Said she never imagined meeting anyone like me & that I'm caring like her dad.

This is a girl I can see myself marrying & I think she feels the same.
BUT something is holding her back.

Last week we met up & she said she wanted to be honest that she has stuff to "sort out" first.
She just broke up with a guy less than a month before meeting me & he's still "hanging around"
Thinks it's unfair to involve me & doesn't want to mess things up between us.
She said she's torn: Part of her says to stop talking to me/seeing me while she sorts it out
& the other part doesn't want to.
I told her I wanted to keep seeing her & support her through whatever it was.
We talked for over an hour & she said okay then was very warm and close.

Yesterday we had plans to meet up but she cancelled and said the same thing all over again.
Things to sort out, confused, not sure what to do.
I again said I wanted to see her & support her but she wouldn't agree this time.
She said let me call you later on tonight (didn't call).

Just wondering how to handle things from here other than waiting for her to figure herself out.
