I disagree, I feel that taking responsibility for your past makes things easier to deal with and easier to move on. Four out of six long term serious girlfriends cheated on me. While I feel that reflects badly on those girls personality, I also take responsibility for my behaviour in the relationship, I was a typical Beta male who didn't hold up my end of keeping the relationship stable. Accepting that has lead to me being a stronger happier person, in an excellent stable and above all, well adjusted long term relationship with a girl I'm desperately in love with.

What I'm saying, is the OP is blaming Social Media for her own issues,in my opinion anyway.
