Why am I so Jealous of everything my girlfriend does?

​

TL;DR : I dont care what you do whatever you wanna do…… why am i so angry about anything you do?

I am a guy and iv been with my girlfriend for around 5 months now. Around the middle of the second month i started getting jealous of things that my gf does that i shouldn’t be getting jealous about. For example, me and her are friends with who we will call Ray. Me and Ray are good friends and i never got frustrated when they would talk to my gf but now anytime they talk to her i get extremely frustrated and extremely jealous and i have no idea why. I feel like crap too because she doesn’t have that many friends and only talks to a couple people.

Around a month back we had a famous entrepreneur come to our town and I knew she was going but with her family and I couldn’t sit by her. Around when it got to around the middle of the presentation i noticed she was only a couple rows ahead of me and was sitting with Ray and they were being friendly and i just got extremely jealous and frustrated to the point where i had to actually get up and leave to avoid freaking out. Even if shes just texting people i get jealous. I feel crappy about being like this because i don’t know how to control myself when it happens and than i feel like a crappy boyfriend because she doesn’t deserve this. I just feel like a crappy human being and I don’t know what to do. I’m open to any suggestions and thank you if you read through all of my crappy problems.

( s.n I am seeing a therapist because i do have depression and i brought it up to him but he hasn’t really helped)

Edit: I was in a very munipulative relationship a while back and i have been just chopping it up to that may be why but i am not to sure.

TL;DR : Do whatever you wanna do…… why am i so angry about anything you do?
