Long distance relationship. I couldn't reach him at night. he says wifi is gone and mobile data is over. he doesn't show me a proof. what should I do?

with my boyfriend, we are in long distance relationship. in different countries. 2 years im with him. yesterday he said he working so like always i waited him till 8pm then he came replied my messages and disappeared. yesterday whole evening and night he was offline at whatsapp. only place we talk is whatsapp. i waited but he didn't even come back to say goodnight. i couldn't sleep any, my messages never delivered until morning. he lives in a house which WIFI have. then at morning suddenly some messages came, i asked him when he sent these goodnight messages, he said yesterday, i said i didn't get any message yesterday. i asked him to prove and he showed me a screenshot, its at night sent by him, he didn't lie. he said wifi was gone, he didn't have mobile data too (the internet paid, not wifi). he said: "i put internet now that im going to work, i recharged my phone at the subway station". i asked him to prove me if today he got mobile data, i asked him to send me a proof that he took mobile data today. (like a message or you know at phones it shows mobile data date) but he doesn't send me. he talked very rudely with me. he said: "u did this once before, and u promissed to not want proofs of me. u really dont trust me huh? but u know last time that u aske me proof I didn't liked" he said. and i said: "i can't trust you now, yes". he said: "u did this once before, and u promissed to not want proofs of me, remember?" , i said: "i don't remember. i never promised that i won't ask for a proof. I don't want proof unnecessarily. but now i need a proof" i said. but he said: "i do remember", then i guess he looked our previous chats and said "yes you didn't promise" then i asked him to send a proof of mobile data. he said: "what if i say no? then i lied to you, because i will not prove anything. but u know last time that u ask me proof I didn't liked. yes i lied to you, u want to believe that. then i lied to you, because i will not prove anything." he said.

yesterday he confessed he lied. he said: "i can't prove it to you, because it was a lie indeed, i turned my mobile data off yesterday, im saying that because i recognize i was immature with you, and u don't deserve this. no, i wasn't at home, i went to the board games event, and since i knew i couldn't talk to you properly , then i turned off mobile data. the only proof i have, is that i added a guy on whatsapp. i knew you would not like it, so i lied,"
