Does he like me?

So, let me say that this is the same guy I’ve liked and written about in my previous post. He is my supervisor however both him and I were promoted at the same time; we’ve worked together for about a year. I got his number from a friend a couple months ago, and texted him regarding work: he responded, our convo went for a few minutes, it died down so i simply hearted the conversation. He double texted twice 45 minutes later ( mind you this was around 11 at night) and talked until 1:30 A.M. Whenever i see him at work he always says hi, and seems excited to see me- he said my name in a really excited tone. Anyways i’ll cut to the point, recently we had a conversation where I first had apologized for bothering him, he responded shortly after with, “Youre not bothering me…”, the convo continued and I disclosed something personal yet work related and said “between you and me….”, he responded with: “Anything you say stays between us, you can trust me and I think you know that.” The conversation continued on, and then around 1 he stopped responding because i’m assuming he fell asleep? I’m really into him but I feel like I’m always initiating the convo, however he puts a lot of effort into the convo and reciprocates the energy! I really want to ask him out to drinks but I’m worried he might reject me. Men of reddit, is he into me?
