We went on a date and he opened up about his past and showed me important spots to him then we ghosted me. Then told me he started dating someone else. Was he just using me

We were texting for 4 months straight then we met up and he picked me up and planned everything. Now I knew him 10 years ago and we dated 2 months back then. So it seemed like it went good we were talking and he showed me where his last apartment was and showed me where he got sober and we actually talked about seeing a show then the next day the vibe completely changed and our texting everyday became spaced. Then no reply for a week so then I reached out and asked him and he told me he’s been busy with work and just started dating someone and how this is all new to him and he didn’t want to worry or think some way and he shouldn’t have just dropped off. He later told me the reason why is because the vibe felt off yet and he’s been trusting that feeling more when he gets it. I was nervous but I don’t think I was acting any different then I have the entire time since we started texting again
