<human>: We have been apart for just under 7 months now officially. There was fault on both of our parts, but it was primarily mine due to a lack of effort caused by a few factors including anxiety and nutritional deficiencies. For a couple months afterwards she was back and forth between it being what she wanted and not what she wanted.

We kept in contact and acted as friends for a while, although on her part it felt insincere/forced. I believe this is because of her mixed feelings towards what happened as well as feeling bad about hurting me, but I couldn't tell for sure. I was trying to act happy the whole time, doing small things for her and treating her nicely thinking that that would help her see that she made a mistake.

She began a relationship with someone else even though it was pretty clear we were not on the same page on where our relationship stood. She also hid that from me for a little over a month while acting as if she was still my friend and nothing had really changed the past few months.

I believe I have made myself who I need to be for her and improved on all of the areas that I could have failed her. Communication is minimal/nonexistent currently and it is pretty unclear whether or not she wants to do so. What can I do to show her that I've become a better person than the one she left?

We had been together for about 1.5 years before breaking up

Can you provide a brief overview of the text?
<bot>: I fucked up, but I know how to not fuck up anymore. How can I show my ex this to try and spark interest again?
