Addicted and in a relationship in distance

Since 4 years i am in a relationship in distance with my girlfriend. Porn always had a huge impact to me and also to my girlfriend because she knows about my addiction. We had a few times where we almost broke up because of it but our love always kept us togheter. Obviously it is super hard for her to know i am addicted to porn but she also supports me always. The last time we were close to break up was 9 months ago. Luckily we didnt break up. From that moment i had the desire to deal with my addiction. For 3 months i stayed clean. But after that i slipped. And since than i struggle. Obviously the distance between us makes it even harder for me. The moments where i am togheter with my girlfriend i spend almost no thoughts on porn. My problem is that when i am alone, than i start to struggle. But my desire is to dont struggle anymore because i want a healthy relationship and i want the best for me and especially for my girlfriend. I am new here and this is my second day. I already fee that this exchange is a very supportive way for me to handle my adddiction bether. To tell my story gives me strength and a good feeling about my journey. If somebody is in a similar situation i would be happy to exchange our storys and talk about it. Because when i learned something in the 3 months i did nothing, than it was that talking about it really helps.
