I'm sorry she's still not in the mood to talk. Just keep in mind - as much as you want to talk, she does not, so reaching out more is going to push her further away. I'm sure she'll approach you again if she wants to mend the relationship.

As for the strap-on, it depends. A future partner might not want you to use the same strap-on with her that you did for a past partner, even if all precautions are followed. I'm not sure I'm going to allow my girlfriend to do so...I may insist on one that she has never used with anyone else because I just don't want her to use anything with me that she has used with another girl. You know?
