I am a firm believer that jealousy is not a thing to be risen above or overcome. Listen to that shit. You WANT something. You feel UPSET about something. You want to advocate for yourself over others. you don't have to get over that. let it tell you what you are not getting enough of and ask for that shit and if you're still not getting it after doing so, you can put your foot down! You can have a fit, say that things aren't working, be an emotional wreck, beg for lots of reassurance, demand quality time, walk away from the relationship. You can be a jealous person!! It's literally okay! Own that shit. Some partners even find possessiveness or jealousy in a partner to be very endearing or attractive and it makes them feel wanted. It's okay to want shit. It's okay to need to be special. You are!!!
