What am I missing?

So I met this guy online and we’ve been talking for a month haven’t met in person. He’s been telling me all the things a girl would want to hear, he wants a relationship I’m everything he’s ever wanted calling me babe, this and that…And recently some things regarding his ex have surfaced and were obviously an issue for me, and when I expressed to him how they bothered me he did a 180 he went from being sooo sweet to now he’s dodging a bullet with me, im crazy, my ex was rite about me… so obviously I don’t respond and it’s pretty much over… two hours later he randomly send me a tick tock lol what am I missing here?
