Are multiple humble requests equal to begging?

I have an argument with my girlfriend 2 months back, I have apologized her multiple times although she had forgiven me but she stopped to contact me and i don't know why? I had planned a lunch for us as we already had to do and requested her multiple times for meet up(non-physical) but she said no? Should I leave her and move or i still do more requests and apologies? Because now I feel ashamed of myself that why are you requesting so much? Are you insane? And why I am hurting my self esteem why? Give some insight pals...
