Break up

My gf left me 3 months ago over some minor issues. We were together 17 years and have 3 children. We did not talk for a while, only about the kids, but now we get on great. Sometimes she's flirty and sometimes not. She knows I want to have another chance and I have sorted out the issues in question via a therapist but she has not as yet said its a definite NO. I did text her apologising for everything and that I want to make it work which is why I got help. Should I just bide my time and hope she sees the new me? I don't want to keep pressuring her as I don't want to push her back.
