I find myself in possibly the best communicative relationship since I can remember (if ever) going on over a month now. On the subject of trust we've had a few discussions that helped the both of us work that well for us as a couple. We both come into this with insecurities and concerns (as most do). She comes from a relationship where her partner cheated on her and I come from one where it was going on behind my back and I ended up feeling really dumb for not noticing it sooner. So I recently told her that I totally understand her concerns and if at any time she needs it, to just ask for that reinforcement from me that there is no one else. Even though we know each other to the point of real trust, it's good to "touch base" on this from time to time to really get that from your partner that "all is well".
