My fiancé and I have been together for a minute now and I have been jealous in the past but not badly like this. I am a homebody and he likes being social so it’s normal for him to do things without me sometimes (he always makes sure I feel safe when doing that.) Something recently switched in me. Our friends wants on a short trip to mexico (just for the weekend) and I really didn’t feel like getting a dog sitter and going just for the weekend so I told him it was okay that he went without me bc I genuinely did not care. Idk what it was but after about 24 hours of him being gone I lost it. I was scream crying, I felt abandoned and my anxiety went through the roof. I didn’t not sleep for 3 days (only for like 2-3 hours a night) because of how bad my anxiety was. He would stay on the phone with me as much as possible while he was gone but we were both kinda shocked at how I was feeling and acting because this has never been an issue before. I was brought back to pat relationships swearing to myself he was cheating even tho he has never given me a reason to think this for a second and I know this. I thought once he got back home I would feel better but now. My anxiety is still there. I have never had anxiety like this in our relationship until now. I feel very needy. I need extra reassurance and I constantly feel like I can’t get enough attention from him even tho he’s acting like how he always has. He’s a a good man so why all of a sudden and I feeling so anxious. I want it gone. I don’t like feeling so insecure like that and wish I knew what actually made me switch. Anyone else deal with something like this before?
