My gf still talks to her ex and I’m not sure how to deal with this.

So I’ve been on a relationship with this girl for about 8 months, there had been many good times but also some difficulties. I’m 26 and she is 24.

A few months ago, she got drunk with one of her ex’s (we were on different cities that day) and she told me that she left him hug her the entire time, but she assures me that nothing else happen, even after he tried to had sex with her.

A few days ago, she told me that another of her ex’s started to message her again (he lives on another city), and she is keeping the conversation with him. For as much as I know about him, he cheated on her, but she also cheated on another of her ex’s with him, so I’m not sure what to think about this.

For one side, I think is possitive the fact that she is telling me these kind of stuff and not hidding it to me, but by the other hand, it makes me feel a bit insecure about what to expect from the relationship.

I’m trying to handle it on the most mature way possible, but not sure how much of this would be OK to tolerate.

In addition to this, she is frecuently mentioning the fact that she had a lot of sex with that guy on its time, but she keeps refusing to have any sexual contact with me since six months ago.
