AIO – now ex bf said I failed his test and blocked me

I just want to get this off my chest.

For context: I (35F) and my now ex (46M) met on a dating app and we've been exclusive since Nov last year, long distance. Everyday was perfect, he will update me with his whereabouts, he will send me sweet messages, said I love you's and did video calls. He planned to fly to me to visit, we already made plans for future. Anyway, then last day he sent me these messages out of the blue and claimed I failed his test then blocked me. Also, he already did this to me before – saying like we will not work out and blocked me, but unblocked me the next day and said he was drunk and he's sorry. I know he's drunk during this convo.

Should I have known that he was testing me? How can someone play with your feelings so easily. It's immature.

Did I overreact on how I responded?

*my apologies to these cringey messages. Here's popcorn🍿
