Please Don’t Disappear on me

I’ve just barely started seeing someone who is 12 years older than me. We’ve been talking for a while and I had asked what he was looking for and we both landed on looking for a relationship. We ended up sleeping together on the second date, it was really sweet and lovely. That was Saturday night. Since then, he’s been slower to answer texts than usual. I mean, hours at a time. He’s watched my story on *** though. He said he was exhausted before so I am trying to chalk it up to that, plus he works 12 hour days. It’s only been a day or so after all. This being said, I am anxiously attached and have been dealt very bad hands when it comes to dating and relationships. I’m really anxious and worried. I feel stupid. I just need someone to talk to about it.
