My boyfriend is hiding me.

My boyfriend hides me from his friends and it makes me feel so

f-ing bad. I talked about it with him before but we cant seem to find a solution. He says he hides me because he's scared of getting bullied but that just makes me feel even worse, am I embarassing to him? Is he ashamed of me? He says no but cant answer me why he is so afraid of telling friends about my existence. And the worst part is that this issue wasnt there before this girl came into his life. Most of his friends know about me and it didnt seem to be an issue but now this girl he's always playing with. She lives in another state and they always play games together, he spends more time on the PC with her then with me, they tell eachother that they love eachother. He deleted everything about me in his social Media and has matching usernames with her. Everyday when I sit in his bed and listen to him talk with her I cry and he always calms me down and reassures me that he is not cheating or planning to leave me and that he only sees her as a friend. Am I just jealous or is something actually wrong? I dont know if I just overthink too much but it all just seems so sketchy. Please tell me what you would do in this situation.
