Trust issues

Hi everyone,

I told my gf of almost two years last week that I watched porn and masturbated daily. I've now been PMO free for almost a week, and I sought out a therapist, because I've also struggled with depression and suicidal thoughts in the past. I've been trying to demonstrate to my gf that I'm committed to leaving porn in the past, so I've been keeping her updated on my reboot. Today, when I told her that my first appointment with my therapist went well and that "I really like talking to her," she basically said that she was afraid I was going to cheat on her with my therapist because, by watching porn, I was "seeking out different women every day." I don't know the best way to explain to her how my porn addiction had more to do with how I was using it as a mood booster, rather than any sort of dissatisfaction with our relationship or sex life. Thanks for reading and for any advice on how to help work through this with my partner.
