Is there a connection between porn addiction and emotional dependency + emotional instability?

Hey guys, I'm gonna get to the point quick.

Whenever I am in a relationship, I'm only focused on the girl. I don't really care about anything else in this time. I do watch porn when I am in a relationship, but not so much. My whole emotions seem to depend on the girl and this is how I lost all my relationships - I pushed all my ex girlfriends away from me. I'm just wondering if being abstinence from porn could solve this problem?

The second question: I've gone through a lot of shit in December 2020 and in January 2021 I lost my girlfriend. I'm all alone right now, no family, no friends - she was all I had. From January to this August I've gone nuts several times. I wrote her letters and send her some messages (like "please come back and help me", and some manipulative stuff like "I'm going to change, and I did this and that"), and I regretted all of these actions afterwards. It was like that somebody else took control over me. I didn't recognize myself anymore and I feel very, very bad and shameful. I hate who I am.

Could both of these problems be related to porn addiction?

I don't get past the 7 days..

Thanks for your post, I already know that video.

I'm just wondering if there could be a connection to porn addiction, because I found this:

"a neurological study of addictions shows that not only do known chemical changes occur in the brain at the onset of addiction, but anatomical and pathological changes can also occur, resulting in hypofrontal syndromes. These syndromes include: compulsivity, emtional liability, impaired judgment and impulsivity."

I just don't know how valid this is... I'm unsure if I'm a psychopath that did all these crazy things or if it's partly because of my addiction...
