My sons dad and I separated 10 months ago but were on reasonably friendly terms until recently. An argument started about something unrelated to what I am asking now but my ex partners daughter who is now 12 and I have known since she was 3 accused me of not including her and not doing anything with her after my son was born when she was 5 and a half. I feel this is completely unfair as I have always made sure to include her in everything but when I had a new born I didn't have the time I used to have to spend with her and she is now holding this against me like I'm this horrible ex step mum. I know she is only 12 but I feel so hurt that this is her opinion of me when I have done so much for her. It bothers me so much I don't know how to let it go!
