Yea I agree with you. Reading everybody’s comments about her being a bitch may be correct but it’s understandable because she doesn’t know how to handle it. All she wants is to be understood but when her boy friend found out and then her friend puppy thingy was the cause of it it broke her because she trusted them and then it all went down from there. She built up a wall and her defense mechanism was taking it out on others. She’s hurt and doesn’t know how to handle it. I honestly think she needs a break from all this and needs to stop dragging it out like you said. She needs to make up her mind and make a decision whether she wants to continue doing these things or not. That’s how she’ll truly get better. Everybody makes mistakes and some just don’t now how to handle the pressure from them.
At this point i feel as if all their relationships are toxic and confusing, i do agree that myb the mc is toxic but i mainly think she just doesn't know how to handle the situation she has brought to many (and wrong) guys into her life. she also needs to make up her mind if she wants to forgive him for what he did in the past or not IMO they should not continue their relationship until both of them know for sure and if she stays unsure then their relation should just stop
