Boy issues help

Ella-Paris • ❤️❤️❤️
Okay so I like this guy so much. Yes we met on tinder but we've been on quite a few dates and one night he texted me saying he was in my area and he wanted to chill. So it was midnight when he picked me up and we ended up going to a mountain and having sex in his car. He said he liked me etc but he hasn't texted me for like 4weeks. The sex was like 2 months ago. What do I do? I feel like I'm annoying him if I keep starting to conversations. I'm 15 and he's just turned 18.
