Why is he so angry with me?

[MrOracle]

This guy has more red flags than a Chinese parade. He hasn't changed, and he clearly doesn't really want to be in a relationship. He's not comfortable being "tied down", which is why he has a reputation as a cheater: HE'S A CHEATER. He's also a narcissist (he really only cares about himself), which is true for nearly all serial cheaters.

You've found yourself an exciting "Bad Boy" and you're trying to make him into a Good Guy - but that NEVER WORKS, and he's already fighting back against it. That's not who he is or who he's ever going to be, unless HE decides, on his own, to change. There is nothing on Earth you can do or offer that will MAKE him change. It doesn't matter how much you like him or how well you treat him, he's broken and doesn't want to be fixed, and so he won't be.

So many women do this (try to fix a Bad Boy), and it NEVER works, and they always end up getting hurt - and if they're lucky, the hurt is ONLY emotional, but some get much worse than that, because Bad Boys are BAD, and they do bad things.

in my opinion, there is zero chance of a good outcome from this relationship. This guy is selfish and self-centered and he likes himself just as he is. These are exactly the kind of men that you should be able to filter OUT of your potential dating pool in 20 seconds - but so many women just won't do it, because he's "exciting" and "mysterious" and gives her butterflies - yeah, that's called DANGER.

You can do what you want to do - you probably are going to ignore this advice anyway - but if you continue with this relationship, you're going to pay a high price. He's almost certainly going to cheat on you, and lie to you about it, but if he's angry already, he could also hurt you physically, or destroy your property, or steal from you, or whatever. Regardless of what you SAY you want from a relationship, your CHOICES are leading you right down that well-trodden path of being used and abused, and you seem to have no awareness of this, which tells me that this is what you find comfortable and normal. If that's the case, then you should already know where this leads.
