Guld found Myung and Isamu in a romantic moment, his Zentradi instincts of violence took over. He beat Isamu which from the looks of it knocked him out cold, grabbed Myung and ripped her shirt off. The flashback doesn't make it clear as to whether Guld actually did rape Myung or stopped himself before he could go through with it though. You do see himself stop for a moment and catch a glimpse of himself in the mirror though I can't remember if there was a look of rage or shock on his face.

The flashback suggests that Guld did stop himself and Myung was able to get to safety and was crying in Isamu's arms. But then again, the flashback is pretty sketchy, something more might have happened in the flashback which wasn't shown simply cause it was too traumatic and the flashback only showed Guld enough for him to realise what he had done. And of course the mirror itself could be an actual physical feature in the room or it could be figurative, used as a tool within the flashback to say "look at what you have done."

Myung does sleep with Guld in Macross Plus, but too be honest, I've known a girl who has slept with the guy who had raped her a few years before and of course she's not the only one, there are plenty of cases out there. The girl I knew and Myung were both emotionally fragile so that alone for me, isn't enough proof that Guld didn't go through with it.

In the end the scene itself is pretty horrific and whether you choose to believe he did or didn't is up to you, the viewer.
