so my best friend and her boyfriend have been going out for about a year and recently she found out the back in june her boyfriend was telling some other girl he loved her and being all flirty, this really upset her, but he said he was sorry and he didnt mean it and only loved her, well she decided to give him another chance but shes having trouble forgiving the girl and her boyfriend and its stressing her out, she feels like she isnt good enough and can't compare in outward beauty to the other girl, i realy want to help her but i dont know what good advice i can give
