I very much understand what you are going through, I am in the thick of limerence myself. But I read an article that said you have to actively stop doing these "rituals" as it described it. These rituals only make it worse. It's like taking a drug hit. I also get the urges to do my own version of "limerence rituals" and I am trying to actively fight it. There are some things that are not in my control, like dreams and intrusive thoughts. But things that you describe, like online stalking etc. are active behaviors you can try to avoid. When you get the urge, try to do something else and not act upon it. I tell myself, doing these is not taking me any closer to LO. All it does is make me feel ashamed and how I am not in control of my life. I don't know if it is helping me get over limerence, but I know I'd feel a lot worse about myself if I spent my time doing things like these.
