I posted sometime back on my ex, we have been meeting for lunch on off,I still love her but am getting over her now.

Yesterday we met at a bar I go to, we talked for a while, I was a bit drank and I told her her hair isn't working for her. She got so pissed off,
But honestly it didn't look thst good.
I called and apologised this morning,

I feel bad cause I know it was wrong to say the truth,

I think am just asking if I can get her back.

We were engaged to be married.

Please help me

During a randomly spaced meeting, you took that opportunity to insult her chosen hair style? This is a courting technique you learned somewhere?

"Honesty is the best policy" is the recipe for permanent bachelorhood. If you want to be single forever, go right ahead and be as truthful as want.

Based on your short story alone, I'd have to say "no", it is doubtful any woman would be interested in this kind of behavior.
