<human>: Can you give me the gist of the text in a nutshell?

I found out my girlfriend had been making out with someone at a party while she was drunk 2 months ago. She didn't tell me, but I found out about it this week, and she said she didn't tell me because she wasn't 100% sure and didn't want to hurt me..

I'm hurt like hell, but anyways, I forgave her..

I'm hoping someone who has been in the situation could give some advice on how I move forward.

The night I found out about it I was in shock. I wasn't mad, I wasn't sad. I didn't feel anything, just shocked. I confronted her, we talked about it, she was sorry etc and I told her I forgave her and that it wouldn't ruin our relationship.

But as the days go by, I'm feeling it's getting worse. It's growing inside me like a tumor. It's the first thing I'm thinking about waking up, I won't trust her when she's going out drinking, and I haven't been very sexually attracted to her after I found out.

I love her very much, and we just got an apartment together, so I'm not leaving her. (If we didn't live together, or it was earlier in the relationship, I think I would have ended it.)

I have forgiven her, but how the hell do I move on?
