I'm tired... I'm tired of being the person made out to be the evil stepmom. I'm tired of constantly having to explain myself, my views, my methods, or a situation that a brat of teenager made up.

This is my first time posting but I have read a lot of the blogs and forums and it's really good to feel like I'm not alone. So there's been a lot going on I'll try to simplify a long story. I'm not really sure what I'm looking for, advice or just to vent but probably both. I met my DH 3 1/2 years ago. At that time SD was 9 SS was 21. I'm mad at myself foe sticking around when the I saw the red flags with DH and SD. They had a strained relationship before I came along. No issues with SS. I should ad I have a BD that was almost 21 at the time. Initially I was very into being SM.
