My girlfriend and I broke up recently. She was fed up with me for a few reasons, and she had feelings for another guy. We broke up, they got together, and we remained friends. Today, we had sex. She doesn't want to tell her current boyfriend. Should I just drop it and forget? If she never tells, should I? Should I confront her about this and ask her to tell him with me?

She badly wants her current relationship to work. And I think she believes I'm sabotaging it by confusing her feelings. I'm doing nothing on purpose except acting on my feelings for her, which are obviously still existent. But I didn't have the integrity to not have sex when my body wanted me to, and we were together. She refused to orgasm, but we definitely had full-on sex.

It was understood that she was fantasizing about her new boyfriend basically the whole time, but I can't confirm or deny if she thought about me at all. She wants to take things slow with me, and I think the only reason she agreed to have sex with me is because it would allow her to imagine having sex with him.

I hate myself for this, and this is going to make seeing her awkward in a different way than before. I have to see her every day (school), but the interactions will be more tense.

I know she wants her current boyfriend to love her, and she no doubt feels that this would ruin anything between them, especially so early. Maybe the best thing for her is to tell him after a year that she cheated right at the beginning and never again. That would prove that there is trust but also that she cared enough to stay with him.

I don't know. I've never been involved in anything like this. What should I do?

Move on, don't contact her again, you're an enabler to her self-destructive behavior.

"And I think she believes I'm sabotaging it by confusing her feelings."

No, you are both sabotaging her relationship with your selfish behaviors.

You need to cut contact with this girl and move on with your life.

She needs to own up to her behavior to her boyfriend and let him decide what to do.

Why would you even do that or want to be with someone so dishonest?
