Me and my ex dated less then a month, the reason she broke up with me was becouse i hurt her, she says i talk alot about other girls and she assumes i like them and after we had sex i couldnt feel anything for her and i told her how i felt and i told her it was a temporary effect she got uptset ,two weeks after we broke up.

One month later she has sat by my side and she asks me what im watching on my phone ( it was a gameplay) and i say " a game" she responds "i know its a game ,im asking the name" and i just smirk and ignore her, she starts sayng that i was nice last friday but now im being rude and she never did anything wrong to me and the my "attempt" of tryng to get her back and useless becouse she dint want to date with me (i dint even said anything or tried anything physical , just ignored her) she kept sayng she dint understand why i was like this and kept sayng she never did anything wrong and i always hurted her and i replied "then leave, not forcing you to stay here", i was starting to get pissed off and she said "you said to me "you are trash to me" but i never hurted you and i was always nice i kept tryng to be your friend" (she treats her friends like dogs, making them following her everywhere while she keeps talking about her life) wich i replied: " yes ,you are trash to me you lied, you hitted guys infront of me to piss me off and you and your boyfriend were smirking while you were poiting at me"

She starts to cry sayng thats a lie and that she cares for me and that wants to be my friend,(my ex never talks to me or asks me how im doing, she only talks to me as a last resort, when i try to talk to her she just makes small talk, never attempts to make a conversation)

In the end i hugged and told her she was not trash and to be friends becouse it would be better for us.(wich i reggreted in the end and shoulnt had tried to comfort her and just ignored her cryng)

Later that day she was the same.

One thing that i dont understand is that she tries to come to me but turns around and go talk to other people.

What should i do or shoulve done?
