Fear of being ridiculed
My boyfriend tried to breakup with me 2 months into the relationship with all the "It's not you, it's me" bullshit. That was right after I recovered from a serious illness. A******, I know.
So I was there trying to cry, saying that I love him and stuff, give me one more chance blahblahblah. It was actually to save myself from being ridiculed by our friends for only lasting 2 months in a relationship.
