I think you can get her back, but u have to allow her to see what it’s like without you. Begging and pleading with her to stay is just going to push her away.
Even if it hurts give her the impression that you’re strong enough to live without her (you are, you’re doing it right now) and give her space. She needs to respect you. IF she doesn’t respect you, you’ll be in this situation in another 6 months.
If y’all had a good relationship and you were good to her she’ll come back.
And when she does hold her to the same standards she holds you to.
