Hi guiltier

I'd say that the half of what she didn't apologise for/what came out could be a positive in strengthening your relationship with her.
If she means part of this to be about how you behave towards her then her perception might not be the whole truth anyway, and maybe she needs some reassurance.........sometimes our perceptions don't reflect the total reality, but some reassurance could help.........everyone is going to need reassurance from time to time.
But if you have pushed people away in the past..........maybe she is hesitant to talk to you about some things.........in which case a (constructive) "heart to heart" about the "here and now" inc. how you've perceived things, and how you'd both like things to move on, could really help her in opening up more and help move your relationship with her forward. And forward to an even better level than you thought it was at before. This can be a step in the right direction

But.......how you opened up/expressed those feelings........please don't regret that.........minimally it could have "opened the door" to building on your relationship with your daughter.........but otherwise you are starting to talk about your feelings more, and that has to be good!!!
I don't know how much more you will or won't want to tell your daughter and whether that may change over time, but absolutely keep talking about them to someone, to anyone, to us!!
