I made a huge mistake.. 💔

So back in September I broke up with my boyfriend that I thought I was going to eventually move in with. I loved him so much. He changed and started treating me terribly and we needed to break up. It made me very sad though. I missed him and how our relationship used to be. My friends decided to make a tinder account for me but I was still 17. You have to be 18 to use that app and it freaked me out. Like I didn’t want to get in trouble with that. But I was so hurt over my ex eb (people call him eb because he hates his name elbert) eb is short for Elbert Bartholomew. But anyways I just tried it out. There were so many older people and I never liked anyone bc that was all illegal i think😂 I accidentally liked this guys account and he was 22. He matched with me and that was the only person that’s ever messaged me so I was like okay fuck it imma talk to this dude😂😂 I ended up having an amazing conversation with him. He made me feel so much better. He wants to be a nurse like me and he had his whole life planned out and had his shit together. He didn’t ask for nudes or to fuck me or anything. He asked for my number and I didn’t want him to leave yet😭😭😂 I started texting him and idk I just got feelings for him. He’s so sweet and attractive and so smart like I was blown away. I let too much time go by and I didn’t tell him I wasn’t 18 and I got scared so I told him I was in college and I’m still a senior in high school. That was the only thing I lied to him about. We started hanging out and he treated me so perfectly but now I didn’t have the guts to tell him. Ugh we both fell for each other and I wanted to tell him. I just turned 18 now and I was only with him 2 months before turning 18 but I was scared he was gonna hate me and leave. I broke up with him 2 days ago and haven’t texted him. I just had to leave bc I didn’t want to destroy the image he had of me. It’s not fair to him. He deserves a girl that is older and is actually in college 😂 ugh it hurts so bad but I just can’t tell him😭
