number Lets break down this whole thing into simple facts (according to you story). 1 she told you that she loves you, slept with you (and cheated on you) 2 She told another guy that she loved him, slept with him (and cheated on him as well) 3 You want her back (even if she cheated you and the other guy as well) It appears that she loved no one, neither you or the other guy..... One thing I learned in my experience of going through relationships over the years is the fact that 'saying and actually doing it are two very different things. You are truely loved by someone when she/she actually does whatever she/she says(or said) or at least puts a sincere effort to live up to what she/he says(or said).' Know that you are NOT LOVED at all when the words he/she do not match with what he/she does. AND it absolutely dumb idea to want to be with someone who never really loved you (unless you have sinister plans in your mind).
