<human>: You date a girl for 1.5 years, and it's absolutely fantastic. You both find so much in common, work very well together, have a ton of fun, very romantic. However, one little thing happens (something you say by accident, or miscommunication) and everything goes to shit - "You don't care about me. This isn't how I imagined this relationship to go. We are never on the same page", you ask "why?", and they explain this accident or miscommunication as a reason, but say it's "much more than that, there are many reasons" and remains vague.
She goes on to tell you that she wasn't happy for a long long time... even though you know that you are both having so much fun and romance every other time. It is obviously a lie... I mean, why didn't this come up before? Were they "faking" having so much fun and romance? or they just making up BS to make you feel bad about yourself? Then they make it sound like they are breaking up with you, and they don't accept your apology, and watch you as you try to keep things together and make it up to them. You try to apologize and they just don't accept it.
That makes no sense to me as a guy. Why not say "look I am sorry, this was a miscommunciation. I didn't try to make you feel bad, and I am sorry that that's the way you felt, I won't do that again". Why can't it just end there?

Alternatively, you agree with them that "yeah you are right, we weren't on the same page". Then they accuse you of "not caring", and "not working hard enough for this relationship". There's just no way out of it.

Can you condense the text into three sentences or less?
<bot>: Why do girls get pissed off, and then make up this scheme that they were not happy with you for many months, even though that is not true?
