Help me

So I’ve been talking to this guy for 64 days sence November and long story shout he’s 15 I’m 14 we live really close to each other and we haven’t meant Bc he’s been grounded for grades. He had a spare phone tho but his mom found out and took it away so now I’m doing his streaks.. were not officially dating Bc I said I want to meet a couple of times befor and stuff we call or use to call and talk on the phone and ft before he got his phone taken away. I really like him Bc I have a background of depression and if the love his away I start feeling sad so like everyone who’s a guy that talks to me that is I guess nice.. I kinda start liking.. so Any ways I started going his streaks on snap.. one thing led to another I found conversations with just so much stuff he talks to a lot of girls.. and that’s fine I mean I have guy friends but I found stuff like even talking to his guy friends that’s yes he had had sex.. told me he hasent. Told me he hasent did drugs I all ready knew he did and he said only once I found out like 1 1/2 weeks ago he took drugs and ran away.. woke up in a ditch and when u finally got home his mom was just freaking out and all this.. next I have him talking to this girl name Haley she sounds photos now similar December 8 he said I need u Haley because I want to be here for you because you’re the best thing that has ever happened in a while... then she says I thought I could do live but I can’t... then the conversation just gos on... he then posts a pic on his story saying “it’s 2018 I’m glad to have her in my life” hailey slides up and says “who” he said “U” ... I don’t know what to do I need help if I let him go I have no one and will be all depressed and I don’t know
