My boyfriend and I have been together for two years, and things were going great. But last month, I went to a family event, and my distant cousin, was there. We've always had some flirty tension, but I thought it was harmless. That night, after a few drinks, we ended up kissing. Then we slept together. I couldn't believe what l'd done cheated on my boyfriend with my cousin. Now, every time my boyfriend looks at me, I feel this crushing guilt. I want to tell him, but how do you even admit to something like this? Do I come clean and risk everything or keep this secret forever? I'm completely lost.
