<human>: Can you succinctly summarize the text in 1-3 sentences?

A little backstory: I'm very friendly with a few of my coworkers and one of them I started to become interested in. We text a lot, almost daily, and hang out fairly regularly. One time, we were supposed to hang out in a group but one girl cancelled so the two of us just hung out at my place together. We got really drunk and he was very flirty the whole time-as in, when I got him set up into the guest bed he would just pull me down in with him. One thing led to another and we ended up watching a movie in my bed, where he kissed me. Unfortunately I was already half-passed out and didn't expect it, so I didn't reciprocate very much and just mumbled (huge mistake on my part). He left and nothing really came of it. 

Fast-forward about a month and a half later. We are still hanging out and I'm starting to like him more and more, but the little anxiety voice in the back of my head keeps stopping me. I don't really take the things people do when they're drunk as an indication of their sober feelings, so I don't feel comfortable using that as a gauge of his interest. His friend has told me that he believes my coworker is interested in me on more than one occasion, but even he admits that it's just speculation based on the fact that "[coworker] is happy around you and he's never happy". I'm thinking of inviting him over to watch a movie and have a couple drinks this week, but I'm still super anxious that he will say no. Part of it is that I am an overweight, not particularly attractive person and the other part is that this guy has admitted to being incredibly dense when it comes to flirting. Based on the background, do you think it is worth it for me to give it a shot?
<bot>: I'm majorly interested in my coworker, but he's so obtuse and my anxiety is taking over.
