Why are the "nice guys" so unsettling?

I was talking to guy for a week, not even. I think it was six days. I should've known something was abut off because on the app I didn't respond fast enough and he was like "well ok, bye guess you are too busy to talk" it had only been like 2 hours. I brushed it off thinking "maybe I was abit rude' so he asked for my contact information. I gave him my snap, and we started talking.

Mind you I have a kid (infant) and a full time WFH job. He knew that. He would repeatedly message me, I have two phones one for work and one for personal usage. I keep the personal one on silent during my work hours and only check it during my breaks or when the calls have slowed down and my baby doesn't need him. I kept the conversation up, responding and you know being active in the conversations, but every once in awhile he'd give me like a passive aggressive text like I could feel the attitude through the message ya know?

He asked did I want to come over this weekend, but I told him I don't like going over to people's house's the first meet, plus my mom's birthday was this weekend and she wanted to go with her boyfriend. She asked me could I watch my grandma for the weekend, he said "can't you just leave her alone? It won't hurt her" I said she's 98(99 next month) and sge has dementia and she's wheelchair bound she cannot be alone. He was like "yeah, ok, I guess" I told him next week, and not at his place. I looked at the messages the snap this morning cause I saw a notification, but when I went to say "good morning" he blocked me on the app and on Snapchat, so I'm just like.

"Wtf" I mean I definitely dodged a bullet, but Jesus he was doing too much. It looked like he was trying to love bomb me with all these compliments, praises and constant messages. Like already really clingy. I try to give everyone a chance, but those nice guys have this odd pattern of being this weird.

Update. Alit of you have been so very helpful and understanding, some if you clearly felt called out and some were just confused, because I wasn't as clear. I am in no way saying that all guys are mean, it's just that truly nice guys don't have to parade around about how nice they were. As I used below Ted bundy described himself as a "nice guy" Keanu reeves doesn't describe himself as anything lure that, he's humble and people around him call him a nice guy/good person. That's the difference

Also, I've been talking to a new guy and he understands me better since he doesn't always have time to respond as well, since he's working. He texts me every 3 or 4 hours which is fine. He doesn't constantly try to video chat and text me constantly. I made it very clear and even explained how some people can't handle that I have a kid, he understands. So I hope this goes better. Wish me luck 🙏 ❤️
