Have I ruined my relationship?

Anonymous
My boyfriend and I are together for a year and a half. We are currently on a long distance which is being hard on me and I miss him. He is my first boyfriend and first orgasms. I had a really bad day at work and when we talked I kind of went into a spiral and told him some negative things and that I'm unhappy and to have an open relationship cause I miss him and he stopped making me feel loved or wanted. He got mad and frustrated and told me that every time I bring my frustration from work into the relationship and that if I want to cheat I can do it (he was angry). Basically he said it's annoying that I'm anxious about the relationship and trying to sabotage it. I told him its my anxiety talking and got defensive because I was also frustrated by our communication. We spent a wonderful weekend when I visited him last week. I am literally crying my eyes out now cause I feel horrible about the whole thing. He sent me a song after that and a voice message, something that he hasn't done for a while and made me feel left out. I love him a lot he's sweet and kind and I know he never does anything intentionally it was just a misunderstanding. I dont handle his absence very well and get insecure. I sent him a video apologizing but he didn't reply. Don't want to go overboard but I owed him an apology and I hope he gives me another chance. I feel like i ruined it. He says its alright but I know it isn't. What can I do to assure him that I'm happy with me just going through a rough period? My anxiety is really bad now. He found me a therapist which I'm seeing. I'm hurting a lot thinking that I hurt him. Just want to improve our communication so I also feel secure.
