There was a girl in my office some times ago and she had a limb...a defect of a leg i think ..only when she walk others can see that and she is really pretty...she is married to a nice looking guy who is really handsome ...if he needed, i think he had a chance to find another girl better than her...i dond know what kind of love was between them...
Conclusion
If you have a guilty feeling , better not to do it bcoz you have a lifetime to spend with her...will be really tired..if she is really loving you, then think a thousand times before break up with her...
