Advice needed

For those have seen my 5 posts about my stepmom. Sorry for bugging you. If you guys have a stepparent. Whether its because a parents died and the other remarried or you have both parents living but they're divorced.... how did you deal with the fact you have this new person trying to be your parent? How old were you? Did you learn to like them or are you still very hesitant of them? I was 15/16 when my dad starting dating and remarried. At that point I was set in my ways. So when I have this person being rushed in to my life after my mom had only been dead for a yr... and I'm forced to call her mom or I'm " a disgrace" that made me very uncomfortable and upset. My stepmom didnt really do a good "first impression " she was 35 at the time. She wore a very mini skirt and a tank top with 5 inches heels..... i'm not saying sje needed to be saint like but at least be modest.... you're meeting the daughter of a man who had a wife that was very modest and took first inpressions seriously... Do you guys mond telling me your stepparent moments and what happened? Its been 5 years? And I'm still having a hard time liking and accepting her....
