I am 17 years old and me and my boyfriend have been dating for a long time now. He is a virgo and I am a sagitarius. This summer we are planning on moving in together.

My boyfriend has trust issues with me about flirting. He has my snapchat,instagram, etc. He gave me his too. I don't normally check his unless he checks mine. He checks mine pretty frequently. It feels really invasive but I don't complain because I have nothing to hide.

The reason I have extream trust issues is because in the start of the relationship he had no trust with me at all. One night he got upset and convinced himself that I was cheating. I dont have any guys in my social media except for my family members. So there was this guy, and we talked before me and my boyfriend started dating. He came across the conversation and thought it was recent. I just never deleted it. I mean it was on snap so I didn't take the time to delete it you know? So he texted his ex that he had a horrible history with and started asking her about love and shit. It made me so upset. The fact that he talked so much shit and had such a shitty history with that girl, and of all people he went to her. All my trust fell apart. I've been trying to build trust. I have a lot of trust now. But it's not all the way there. We've had sex and he's my first so he's like extremely special to me. I truly love him and I am really trying.

So to get to the point. Today is his first day of work. He is naturally flirty. He's gonna be working at McDonald's. He's gonna be on Window and cashire. I am terribly insecure. I talk to him about it and he just gets mad. So I dont know what to do.
