I have a concern that's been really bothering me. I was going out with this guy for 3 years. He broke up with me about a month ago, and I was pretty heartbroken (obviously), and I still care for him deeply.
A few nights ago, I saw his older brother out at a party. We ended up talking the entire night and getting along really well. He walked me out to my car, and he ended up telling me that he had a huge crush on me, but he could never tell me before because I was dating his brother. Now that his bro broke up with me, he felt he didn't have to hide his feelings anymore.
It was a surprise, but a pleasant one for sure since I was feeling lonely and I kind of liked him too. We ended up kissing, and long story short, he spent the night (and yes, we slept together). In the morning, we promised not to tell anyone, to keep it our little secret.
Well, to make matters more complex, last night my ex called me, going on and on about how he made a huge mistake, how he's still in love with me, and how he feels awful for breaking up with me. He wants to get back together.
What should I do? I still love him and want to get back together, but I fear I will be haunted by this little secret forever. I feel like I should be honest about what happened. Do you think he could ever forgive me for sleeping with his brother?
