Hi @Salojy ,    I can imagine this would feel like a really tricky situation to navigate.  It sounds like you're in a step father type of relationship with your partner's daughter, have I got that right? It's great that you've been able to discuss these concerns openly with your partner as well.    I can imagine that the thought of having unfounded allegations made against you would feel really frightening, and I'm hearing that you have a lot of anxiety around this, and the prospect that if that did happen, you might then be left in a really precarious situation - I'm wondering if you've ever talked to a counsellor about these feelings?   They may be able to talk to you about the likelihood of something like this happening - in general, it is very rare for a child to make false allegations of this kind. Has your stepdaughter ever said anything to you that makes you feel concerned that this is something that could happen, or is this more of a general worry that you're experiencing?    In terms of appropriate boundaries when a step parent starts living with a single mum with kids, it's definitely something that looks different for every family. It sounds like you have a close and respectful relationship with your stepdaughter, which is really wonderful. Some boundaries that may appropriate, and also could be protective for you could include never entering the bathroom while she is showering, for example.    We have some great articles about blended families on our ReachOut Parents page that might be helpful, I'll just link to them here   Rules in a blended family Be the ultimate step parent Blended families and teenagers   What appropriate boundaries look like is different for every family situation and dynamic.
