That's OK I'm not going to lie, I still think about her and I still have bad days even though it's been a while now. But I know that'll go away in time, so long as I don't engage with her again.

Although this was a very negative experience for me, it's also taught me a lot about myself. So my advice to you would be to learn what you need to learn and to continue working on you.

Do not do what I did and try to make excuses for her, or blame yourself. You are both to blame for the situation, the difference is that hopefully you'll try address your issues... whereas she will likely repeat this with the next person.
