If I don’t fully trust my partner, should I break up with them?

I broke up with my ex a few days ago.

But it just feels wrong. We’re still texting and it feels wrong to both of us.

We basically don’t trust each other, me more than her. Like we trust each other in general, but not completely. It’s been broken on each side.

She broke my trust in a way where I’ll never know what truly happened (she hid stuff and I found out details over time, or she told me months later).

She broke my trust twice more again after that, months and months in between each time. I also either find out or can tell if she’s lying or hiding stuff.

I’ve also broken her trust a few times but I have admitted it each time I lied

Apart from that, I think she’s perfect. We share a connection I’ve truly never felt before and we love each other in a rare way, one we’ve both never felt before. She is fighting like hell to save this.

I can’t seem to shake the gut feeling of not knowing what happened that night and it seems to me that I haven’t felt the same level of safeness ever since before it happened.

But I’m afraid of giving up. What if we can work through this.

What’s your advice? We’re broken up, but I’m worried I made the wrong decision.
