Has he lost interest?

I began working at a new job about a month ago. I work with this insanely cute guy, and we seemed to immediately take interest in each other. We started texting every single day, all day constantly, for more than two weeks straight. Our texting sessions were always playful, friendly, and soon flirty. The more we texted, the more we found out that we were very similar in personality, which he approved.

He'd often ask me if I wanted to hang out, which we did a few times at his house. We would cuddle, watch Netflix, and make each other laugh. The last time I hung out with him a few days ago, we shared our first kiss and subsequently made out. Near the end of my 7-hour-long visit, we got a bit spicy and grinded a bit. We did not have sex, but he did see some of my body. I told him at the start of our flirtationship that I wanted my first time to be special and not too early, which he accepted. Overall it was a very nice time, and he seemed to be just as happy as I was until we both went to work straight after.

When no one was looking during work, I gave him a quick peck on the cheek. However, his smile looked fake. He was distant during the whole shift, hardly speaking to me. At the end of my shift, he texted me saying that he was still single and asked me to stop with the PDA, even though it was one kiss. I gave him the benefit of the doubt, however, and obeyed.

The next day, the texts stopped, which was extremely abnormal. I sent him a couple texts, to which he only responded in two words or less. I carried on my day in silence until I went to work. He did not talk to me once there. Barely even looked at me... So, of course, I wondered if I did something wrong or upset him.

When my shift was over that night, I texted him and politely asked what the deal was. He responded by saying that he wasn't over his recent breakup (a little more than a month ago) and needed some time to himself to think about if he was ready to enter another relationship. He told me, after I asked, that he still liked me and that I was like a female version of him, but he just had a lot on his mind to sort through. I told him that I'd be patient and would only talk to him when he wanted to. That was two days ago.

Yesterday he stayed quiet until he spent a few minutes at night to check up on me through a couple texts.

Today was completely silent.

Part of me believes that he didn't like the body that he saw that one day and lost the spark. My body is not a very pretty sight. I am chubby and flabby compared to his fit and toned form. He did tell me that he's a fairly sexual person, but also said that my body looked fine and didn't care how it looked... He could have been lying... I don't know...

Do you guys think that he's still interested but needs the alone time? Or maybe he doesn't like me anymore after all? How long should I wait to confront him, if I even should? Any insight is appreciated. Feel free to ask questions. Thank you.
