I don’t think is addiction. Feels more like infatuation which is why you have missed feelings for him. Maybe you should take some time apart without drooling over each other to make your feeling clearer.

I used to feel this way but when I distant myself for a month or two, having sex with other people I realised my feeling for him wasn’t true. I only had desires for the sex. His lifestyle and ego certainly became too visible to ignore. The sex was too good so we got back but this time I knew it wasn’t love and my priorty was straightened.
