so me(21f) and my gf(20f) went on a brake and during that brake she had sex with someone else and  acted like a couple with her. is it cheating if she had sex during a brake? i thought a brake is to like for us to fix things up. am i in the wrong for feeling like she cheated on me. i asked if she did smth during the brake but she lied abt it i just kinda found out by accident and now i have no trust for her at all. i wanna belive her i do but everytime i just feel like shes laying.also she told me she blocked her but then she unblocked her later and didnt tell me abt it too. is there any way to move past that and go back to normal? i mostly fucked up and im the one whos supposed to fix things up so that she wants to be with me. i was texting with a friend and she got mad at me and told me to block her or else im out and so i did but i found out she was texting some girl from tinder and when i told her to block her she got mad at me and said why am i so dramatic but for me its not okay also she blocked her but later on unblocked her again and got mad at me for telling her to block her. i get that i fucked things up but how come its okay for her to do stuff but for me not. am i actually being dramatic over nothing?
