He said that I came along and perked him up a bit.
I bet you did. Attention from any 20 something would have perked him up.
This is a man who simultaneously infantilises and sexualises you by calling you weird baby names. Gross.
A man who seems hell bent on telling you how hard done by he's been by nasty women.
A man who is desperate to remind you he could get sex whenever he wanted on demand.
Stop wondering what this man's deal is and start wondering why on EARTH you are even entertaining someone like this.
Why did you unblock him? I don't ask that in a sarcy way, I'm genuinely asking. Is it that you were enjoying being pursued? Or that you think someone older must be more discerning or something?
Because as someone about a decade older than you, I can tell you this guy is a run of the mill, chancing his luck 40 something who would be excited to shag a 20 something and is speaking to you this way because he finds it naughty and exciting but doesn't really care who you are. You could be anyone as long as you're in your 20s, attractive and most importantly responsive to him.
Fuck him off. Block, move on.
No good can come of this. Not even just due to the age difference, more due to the way he clearly sees women.
