I broke up with my boyfriend of 2 and a half years it just wasn't working out and I needed my space. I felt like I was selling myself short by settling down so young and he doesn't believe in taking breaks so it was the only choice I had. So now I'm living with my mom and I'm thoroughly enjoying being single. I love coming and going as I please and not having to answer to anyone.
Well call my ex M. When we were together we used to double date with another couple all the time, but since then they broke up and obviously we did too. (M and I haven't been together for almost a month now) but anyway I was at a party with a friend of mine but she went off with a guy so I was just hanging out with everybody else. Then I noticed the guy we used to double date with was there, just call him D. We started talking and apparently we really hit it off? Because we talk all the time and we've chilled at his place a couple times together. I feel really guilty though because he's good friends with my ex and I'm good friends with his ex do it's a really messed up situation. What should I do?

Don't go there! It's not fair on your ex or your friend.. Just imagine how awkward it would be if your ex was with one of your friends, even though you might not care now it would still make your heart sink and you would feel betrayed..
