based on the mentioned subject, “you hurt her several times”.. Move on and focus on how to be better man.. even though you really love it is too late now.. she is happy and you should be to.. you had your chance..
If you would like to elaborate on how you hurt her and what good things she did for you, please do. More details about the relationship, how long it lasted, the nature of it, any relevant information will help me understand your situation better.
