Okay, here's how I see it. We don't know anything about you, other than what you've told us. Since you can't prove what you say, we have no reason to believe you. For all we know you could be an ex-girlfriend of his, or a disgruntled former employee, or whatever, telling lies and trying to cause trouble.
See, that's the thing about the internet. A person can make all kinds of assertions and allegations, but unless you can provide something to back up your assertions and allegations, what you've said is nothing by 1's and 0's in cyberspace. I have no idea who you are, so I have no reason to believe what you say. I'm sure you understand that.
