Why am I so jealous

I don’t know what’s wrong with me every single thing my bf does bothers me like he txtd me and told me he’s going to his cousins bday for a couple hours and it’s not even at a club or nothing I got furious. Idk why I feel like I’m losing my mind. I’m so over protective of him and I hate when he goes to parties or gatherings without me I’m so mad but I played it off on txt like I’m all cool but inside I’m fkn mad asfuck.

I’m so bothered right now he’s always trying to make it to everyone’s birthdays but barely can come around to see our daughter.

So later on I’m supposed to meet with him cs he’s getting us a hotel room so we can spend time tonight but I’m mad that he’s going to his cousins birthday so I’m planning to leave him hanging over there so he can feel how it feels to be ditched. I was like lmk what time u get to th room later so I can come meet u there but I’m gonna make him go buy the room then not go at all and make him waste his money 🤷🏼‍♀️ or if not I’ll wait till late am then show up.
