Relationship help, please..?

honestly when i found out she cheated on me i would have left her then bc if she done it once she will more than likely do it again.i understand u love her ive been in that position my ex bf cheated on me by kissing another girl at a party as far as i knw it ddnt go any farther than tht, but it still hurt bc i loved him.and i will tell you exactly what i was told. if he (she in your position) will cheat on u drunk or not then she does not have the respect that you deserve. if she did it twice already then how are you sure you can ever trust her? and about your anniversary she obviously dont take your relationship very seriosly or she would have made an effort to see you even if she did have a bad day or what ever as a woman my self i knw tht if i truley love somebody i am gonna wnt more than anything to see them on our annivesary if she will kiss another guy like tht than more than likely she may even sleep with another guy you never knw but its really up to you the way i was told if you really truely love somebody then u will love them enough to let them go i knw thts prob not what you wanted to hear but i hope i atleast helped you a lil bit
