Re: 7 year on/off relationship – winning back ex?

Thanks! Answers below, hope you can give more wisdom.

Our fights/breakups were because we kept arguing over small, silly things. Immaturity
Her personality has been very sensitive, complaining & negative & mine became very distant/emotionally off.

[b]Year 2[/b] Long distance. She got depressed left & hooked up with a guy. Apologized & we got back together

[b]Year 3[/b] Moved back. She left 2 months in “were ok but I’m too young for a serious relationship”
Hooked up same guy again & another. 1 month later we back together
The hurt & her personality made me switch off
I kissed a girl she begged me to stay, I did but fights continued
End of year verbally flirted with her friend, she got over it

Year 4,5,6: She was trying 100%, I wasn’t

Year 6 start year I kissed a girl (drunk mistake didn’t tell her)
Mid year split, she went on date & kissed a guy. Got back together.

Year 7 January split over fights + I didn’t want kids (dealbreaker)

Did months reflection, realized my mistakes & changed on children
Met her, explained everything, declared love & told her about kissing girl 1 year ago.
Spent day together was okay but she asked for space.

3/4 phone calls/chat conversations & some romantic gestures like flowers since then.
All has been positive & she says she feels huge change in me but…
