[Addie]

There's this guy I've known for a little over a year but we don't talk alot. We are both 16. Anyways, we met at camp and he stated at me ALOT and flirted with me. He also asked for my number. We flirted over text for a couple months then he kinda stopped texting me. I saw him at the pool once and he just stared at me without saying anything. Then he got a gf. Then they broke up and got back together, then they broke up for good. When they broke up the first time, the guy was like text me so we were texting (flirting) but just for one night. After the second break up, we were texting every day for awhile and we met up at the gym twice and he was flirting a lot. Then he mysteriously stopped texting me in around may or June. He gets grounded from his phone alot and for long periods of time so I think he's still grounded from it cuz he hasn't texted me. Also, he doesn't have a Facebook so I had no way to contact him for a couple months. However, yesterday I got a twitter and followed him. He followed me back and I tweeted that I missed him. He said I miss u too Addie <3 and I said come chill with me and he said aight <3 (this was at around 12am). Around 12am he messages me on twitter and was like hey beautiful!! And I said hey babe and he said ahh what's up my girl? and I said chillin u? We should hook up soon (we have been talking about hooking up for awhile now). But he didn't reply. I thought oh he fell asleep he wil reply tmrw. But the next day (today) he was tweeting stuff and still hasn't replied to me I'm so confused! I thought maybe he liked me and he stares and flirts with me, but now he's not answering me! Idk why. I have a couple ideas: 1. Maybe he just forgot 2. He might not have gotten my message somehow which is highly unlikely 3. He replied and I didn't get his message somehow which is also unlikely 4. He is ignoring me 5. He is offended that i would be so forward which wld be weird cuz he's said rly dirty stuff about me. Idk what else:/ thanks
