YES they do. Taurus is possessive of the people in their life because they’re extremely picky and only associate with those who they value. Taurus has high standards and very rarely do they find people for them to feel safe enough to attach to. Once You become part of the things that make them feel safe and secure they dont want you to go anywhere. You’re “theirs” and Taurus have a hard time finding people that fill the lonely void they usually fill with materialistic things.. This is why Taurus gets attached SO fast and starts fantasizing the future of you two together because Taurus RARELY finds someone that fits their whole check list for the perfect mate. The perfect mate is the romantic (they’re ruled by Venus so yes they still want romance) yet SAFE bet. They value stability and security in a person so when they finally find that person they become so obsessive, clingy, possessive and controlling (Scorpio shadow) because they don’t want you going anywhere. Once they have a stable secure routine with you their insecurities can come up when they feel it threatened and that causes the Scorpio shadow to come out of them. If your Taurus is acting out in these ways its because they feel their safety of the relationship is threatened and because they’re so attached to you and STUBBORN they’re NOT going to let anything ruin that and they can start to become paranoid and lose their practical and logical earth reasoning.
