Amanda I'm so glad you've seen the light and blocked him because that's the only good bit about your posts. I know it can be hard to see the wood for the trees when you're involved, but from an outsider, who has learnt the hard way with situations just like this, here's my 2p worth...
"...then he just suddenly stopped replying I sent him messages and got ignored..."
Avoid sending a message after the previous one, especially if it was asking a question, has gone unanswered. If someone is ignoring your texts they sure as hell don't deserve any more of your time or attention.
"...then he messaged me one night saying "blah blah BS" ...but I just politely agreed for him to take as much time as he needed..."
An open invitation to be treated with zero respect. Your time is precious, start valuing it and not politely agreeing to wait around for blokes who feed you crumbs.
"...another week went by so I messaged him again..."
Shouldn't have messaged him, you left the ball in his court.
"...I got ignored so I asked him why he was ignoring me"...
Stop persuing people who ignore you, that way madness lies! You will lose your dignity and self esteem.
"...I said "just tell me the truth what you really want what your thinking about"...
Oh god, that's way too needy and heavy considering you're not in a relationship with him (not even had the first date!) and he owes you nothing. It's embarrasing, sorry.
"...and he messaged me saying "blah blah BS"
"...so I just ended it there and said to message me in the future if he changes his mind..."
Another open invitation to be treated with zero respect by a man who has shown you more than once that he's not particularly interested in you, but you've told him you're so desperate that you will allow him to booty call you if he's so incined at any point in the future to suit him.
Yup, plenty of more suitable men out there for you
