Hi DefensorDown
She's gone through the spiral and has even threatened suicide, blaming me for not trusting her when she "apologized" for lying, and for me not rewarding her being truthful and owning up to the lies.
Clearly, as you've put quotes around the word "apologized", you know this is questionable behavior. I'll go one step further:
this is manipulative behavior. She lied and wasn't truthful,
yet she blames you for not trusting her. She apologized in a way she thinks is acceptable, but
she doesn't understand that apologies are meant for you, not her. She is upset that you've not gone back to normalcy after this, so
she threatens suicide. Why is she doing these things? Well, these are clearly manipulative tactics.
I'd categorize most of these as blame shifting (sounds like she's gaslighting you too, except you're catching her in her lies). She's doing them so that a) you feel bad about questioning her, and instead question yourself, b) blame can be put on you for these fights, even though your actions have been entirely logical and respectful.
As Pook075 said, the kind of respectful honesty and empathy you seek you probably won't get. Has she given you any reason why she ghosted you for multiple days? Has she given you any reason why she lied to you about what was happening?
You're right. It's difficult to believe someone who doesn't tell the truth. The Boy Who Cried Wolf comes to mind. It happened all the time throughout my relationship, and again as Pook075 mentioned, it's very very likely that this will not be one-off.
I went through a series of lies that may or may not be centered around cheating, but definitely were centered around drunken flirting+ which ended my relationship. I've been trying to process with therapists what happened and how it came to that, especially after I had been so patient and understanding about past odd experiences with other men. I too got ghosted. I too got manipulated, specifically gaslighting, blame-shifting, projecting, triangulation, and generalizations. She threatened to break up **WITH ME** twice after she'd been the one to do wrong. I was told that as a man, I wouldn't understand.
The funny this was, when I spoke to the important women in my life (my sister, my mom, my female friends) they all completely saw my experiences and emotions as valid, and said that being a man or woman had nothing to do with it (they are all feminists). After the breakup, I've begun to understand that I wasn't going to be capable of getting the closure that I was looking for. Instead, I need to (and have been) working on my own reasons for why I was so patient and understanding for things that I never should have been. I have been slowly coming to the realization that I was given a losing poker hand but was going all in because of emotional attachment, not because of the cards on the table. Sunk cost fallacy.
I'm also seeing a therapist who has a Phd in psychology and specifically specializes in personality disorders, and she's been incredible in making me more skeptical of what happened and understanding my part in the relationship. She thinks there was much more lying that I had originally thought. She is skeptical of my ex's every word. She wants me to go NC. She questions my every move, but in an emotionally supportive way (not in a BPD controlling way). I'm beginning to heal. But if there's one thing I've learned from my therapist, it's that more happened than I could've ever known. And that I was too accepting of things I should've never been.
If you sense something's wrong, it probably is. If you sense she's acting questionable, she probably is. Trust yourself and get the help you need. And first and foremost, don't caretake for her just because she manipulates you—you are your first priority. If she can give you the closure you need, that's wonderful. But come in with the expectation she can't, and figure out how to get your own needs met.
