I have been in a lover's relationship with a woman for six years, and now there is a chat record saying that I forced her to sue me now?

Whether you really did it or not, it's been six years, so there is no evidence to prove whether you raped her at the beginning, unless you admit it yourself, but even if you admit it, the evidence is not enough. You won't be stupid enough to admit it, will you? In a word, you escaped the punishment of the law, but you must bear the moral punishment. Just like what you're worried about now is your punishment. She can't sue you. But I despise you.
