Why do guys do this? lol

something strange but funny happened to me. I was talking to a guy for a few days that I met on hinge. and he was saying all this crap. He’s a cop. He was calling me babe saying he wants to be with me, he can’t wait to see me, he wants to spend everyday with me. He’s not here to waste time, he’s looking for his person. I’m his type physically and he likes my personality and he got so lucky with me. He was planning the future with me, telling me I was beautiful every second. All of this crap. We never even met in person yet so I thought he was going way too fast but I was like whatever , I went along with it. I thought it was fishy though. So we’ve been talking for a few days with him saying the same stuff to me pretty much every day. He would send me romantic videos on instagram, telling me I’m all his and I’m all he’s ever wanted and that he can’t do better than me. He was being so sweet. Then yesterday I asked him to video chat and he was like sure babe whenever you want just let me know . We finally video chat and we’re talking and laughing and then all of a sudden randomly the phone hangs up. So I thought his phone died but nope, I go to text him and it seems as though he blocked me and he deleted our match on the dating app, and deactivated his instagram. I couldn’t believe it but I was also laughing. I made a fake number and called him on that and he answered right away. So that’s how I know he blocked me. It was so weird and we were supposed to go on a date tonight. Why would any guy do that?. They just love to waste time. I just laughed it off because that’s the first time that’s happened to me but it was just so weird and strange behavior lol.
