<human>: Well the main question I want answered is in the title really, but here's some more background.

We met 3 months ago, really hit it off. All the kind of normal early relationship things, like getting to know each other, going on dates and lots of sex. I do feel very lucky to find someone compatible but from my previous relationship experiences have not been good at all, especially in comparison.

Basically we had a really long week away together over easter. Just the two of us, and lots of spare time to talk and really get to know each other, it was absolutely great, but one thing bugs me, we haven't spoken about past relationships. The reason I want to share with her, is my last long term relationship (from when I was 19-24) was very emotionally abusive and does mean that I do tend to still be insular with some feelings, sometime I have worked a lot on and my current GF has really been good for helping me get over a lot of them.

From her side, she was telling me about her old Uni days and how she shared a flat with 3guys. She has only really mentioned 2 by name, but refers the 3rd as "the engineer". Now, being a bit insecure still I did end up going through her FB pictures and I worked out that the engineer is her ex, and a lot of her stories from Uni did end up referring to him. I was kind of worried whether it is a bad sign he's been mentioned a lot but with no actual mention of who he really was to her? There's also the minor fact that her banner picture on her profile was from a set taken by him on a lovely looking date.

She is clearly very in to me, and I know the only thing which can ruin the relationship at this point is my insecurities, but is there ever a good time to bring up old exs? Or is it something we should never talk of? Is the picture which is clearly a reminder of the ex an issue? Also we have yet to have taken any pictures of the two of us, and some of my friends have commented that they find it weird there's no pictures of us yet. Is that also an issue?

Can you condense the text into three sentences or less?
<bot>: I want to talk to my new GF about past relationships, is this ever a good idea, and when should it naturally come up in a relationship?
