Problems on my long distance relationship?

[Band]

okay. so. im a girl. call me PI . so im in a relationship with this guy for 4 months now. so i havent met him its LDR. i love him so much and want our relationship to go farther but he's acting weird these days. i know he's always busy with wrestling but, i can feel he doesnt want this anymore tho he says he wants it still. he's not excited on talking with me anymore, he's not sweet anymore, he's showing no efforts at all. i dont understand him now. and he says he's proud of me but cant even get on fb relationship with me, he says he doesnt want to be bothered by people asking question if i get in relationship with him on facebook. but when he's with his ex before. theyre even "married" on facebook. which makes me think that he just dont want to let the people know that im his girlfriend. i dont know if i should end this. im starting to feel stupid and insecure cause he cant be proud of me and he'a always acting cold. please help. what should i do ?
