Mind games? if so why?

so my long distance ex from 2020 decides to reach out to me online & we become cool over the phone and follow each other on social media. He tells me he’s coming to my city soon and then after a disagreement he said he’s no longer coming. Today I found out that he actually did have plans on coming still and he just didn’t tell me. He stayed for a day and then proceeded to go onto another business trip. why did he lie? he also watched my Instagram and interacted with my social media for me to realize that he was here. he didn’t tell me he was coming. He didn’t tell me he was here and he didn’t tell me when he left. I noticed all through social media.
