First of all, Hi
First of all a quote for you to think about.
Don't push any1 to hard, if it's meant to be, it will happen.
Well, For a start I commend you for trying to help Erin accept herself for who she is, but it should've been her start herself on the road to confidence, and you to be there for her. However she may have not done it, so that could be void...
If that makes sense. Oh well I know what I mean
For a start, you shouldn't help a psychopath. Leave it to the people who know what to do.
I feel sorry for you about Erin also not believing you that you didn't have sex with the other girl. But maybe she needed proof.
A;so if she is seeing someone else now, leave it, move on. You seem to have not another chance. And if you really love her. You will realise that real love is just wanting the person you love to be happy, no matter who she is with, and to realise that if she was with you would it ever be the same. Well the same as before you told her you thought you slept with the other girl?
Hope that helps.
I could try to help more on this, but on trying to get a taken person back, im ruthless, dont spoil the life they have.
I hope you find love again.
