If the first guy you were dating was a lying, cheating, dirty, dog, and the room mate gave you a heads up about it because he didn't want to see you used and hurt by the guy, and in the process you fell for each other. After all the first guy didn't earn my respect by behaving the way he did, and the room mate lost all respect for him after seeing what he was doing. Guys on the other hand seem to have no problem with wanting to date an ex's friend. Maybe it's like if you don't want her, she's fair game.
Hopefully you will all have fun meeting singles and try out this online dating thing...Perhaps you’re thinking to yourself, “We’re all adults here. So even if your friend is “OK” with you dating her ex, you are likely going to see a lot less of your friend.A buddy of mine recently mentioned that he might invite my ex to a party that we were going to and asked what I thought about that. And if you want to spend time with someone who has been “spaced” by a friend, that will very likely mean that you will then be spaced from your friend, too.It’s a good idea to go into any romantic affair with eyes wide open.The key to making a prudent decision here is to keep an emotional distance until you have made a conscious decision to move forward with your friend’s ex. We all want to be happy, and most of us are looking for someone with whom to live happily ever after.Luckily, a woman can approach this in pretty much the same way a man does, and that’s where I can help a sister out.Take it from a guy who has been in this tight spot a time or two—there are three things you must do before moving forward with your friend’s ex. Anyone who has had any sort of meaningful romantic relationship can tell you that—over it or not—it would be difficult for them to be around their ex.It's one thing if she decided to date someone you knew, but didn't hang around with... but dating your roomie is almost like dating your buddy or your brother, you know? At the very least your roomie (and/or your ex) should have approached you and asked if you minded. If you guys were together for a long time and were totally in love and the break up is recent, that would be really tough. I was honest with him and told him I’d probably be less likely to go if I knew she would be there. I just wasn’t jumping at the chance to be around her. The question you need to ask yourself, then, is whether it’s worth it. I know men typically like to have control over situations or at least feel like we have control.We all know the difference between a fling and something more. Why not just tell her that you’re going to date her ex? I imagine that most women like to have the same sense of consent.
