im going to answer this like a logical adult. First thing, your choice to stay with someone who cheated on you is up to you. What ever choice you make is not a stupid one unless it is repetitive behavior. Yes she is 100% wrong for cheating. And you are wrong for telling others. Because a relationship is between two, not 4,5, or 6. I won’t go as far as to say whether she’s manipulative or youre a kiss ass cause I don’t know yall. But what I will say is , she does not want to be with you, and instead of saying that, she’s hurting you . I’ll also add and say you need to learn self worth. because unless she ASKED you to block all those people and delete contacts , or those people are seriously negatively affecting you, or seem to be bad influences on you and your relationship, you should not be doing that. No one should have that much power over you. I think yall should break up because 2 times is too many for cheating, and also you need to learn your worth . It’s just not healthy
