<human>: Can you succinctly summarize the text in 1-3 sentences?

24M, 20F.  Dating 2 years.  We were a very close couple, attached to the hip most of the time.  The relationship has always had ups and downs, but recently my trust in her is waning (she smoked behind my back after I asked her to stop, as well as other white lie stemming from her insecurity).  I have been far from perfect as well - she is resentful of some of the things I did (understandable).

We still love each other, but the relationship is dying.  We argue all the time.  We say hurtful things.  We want different things.  I'm not ready to settledown, and she wants prince charming.

Last night we argued again and it lead to us breaking it off.  At the very end we somehow worked out that we'd see each other casually, while beginning to date others.  She mostly brought this up and I accepted.

Reddit, is this a bad idea?  Why did she propose this?
