Answer 1

well u did lie to her and to keep ur relationship strong u got to admit this to her trust is a very important thing

Answer 2

well if you truly do like her and not the other people then you have nothing to worry about, however if you still think about ur ex's then you have some explaining to do because no girl wants to be lied to about her bf's ex's

Answer 3

Talk to her and tell her the truth
