I personally think your therapist stopped before you had a breakthrough-which is the worst thing a therapist can do. The most important thing to do right now is talk with your Significant Other and explain the situation from your POV. Explain to him that you see what he did as rape and that it will be hard to get trust for him again- what he did was a mistake to himself, but to you it's like he broke your trust (my interpretation, sorry if I misunderstood)

You also have to get used to triggers off of things like movies about being raped. I would get triggers from just hearing about kids being abused. I still get them occasionally, but there's a point in you that you have to reach where you work through it. Find a coping mechanism. Mine was writing, maybe yours is painting, or go shooting or boxing. Find some way to get out your emotions. I found writing to be best for my therapist and I because I would give myself a breakthrough while writing and my therapist would walk me through what I need to do next to move on.

I really hope this helps *hugs*
