Am i a Dating Pessimist?

Just wanted a place to rant for a second, feel free to comment your opinion. So i think i literally have been single all my life cause i literally have no tolerance or patience for bull shit. I spot red flags from a mile away. Im 22 and have never been in a real relationship. I like to consider myself a hopeless romantic but i know my worth and what i want in a relationship. This situation with this guy recently literally has me thinking fuck it i’d rather be single at this point and turn em all down 😭 basically this guy i was interested in for a little second lied about traveling then FaceTimed me in his room and had no shame in even asking me to help pick an outfit for him for an outing with his friends 😂😂😂 like what i though you were in a whole other country sir and didn’t even care to be sneaky which idk if thats a good thing or a bad thing but all in all he’s a liar and about something so freaking stupid and pointless. I didn’t even care to ask why he lied because wtf is the point of that i wouldn’t believe him anyway so i basically just gave him dry convo till just pretty much ghosting him. Now he’s blowing me up like is it not obvious why I’m turned off from him?

Should i say something or just let it be?

Update: I said something to him so he could stop blowing me up but he literally tried to gas light me then got mad when that didnt work so i blocked him 😂
