That is awesome. And I am so proud of your (as you should be too) for taking the first step. And you should be very proud of being aware of your behaviour. And I just want to clarify too (so there's no room for misunderstanding) that I don't mean this in a patronising way. I've been where you and I have reflected on my own behaviour and there is something freeing about knowing you are in control and can change it. I hope this person can see how you are feeling and work towards mending the relationship. And know you can hold your head high, because you've done the right thing
