I think I like my best friends ex. What should I do?
Have you ever considered getting back together with your boyfriend?
No, the idea of reconciling with him is too freaky and weird.
While we can't always control who we are attracted to, we can control our response. If you find yourself being attracted to your friend's ex, then you should speak with your friend if its okay for you to go ahead and pursue them or not. You should place your friend's interests first since you getting with the ex could make for a very awkward situation in your social circle.
my friend? Screw that I am going to go after him if I want.
You two might really have issues if you do this without talking to her first. It might cause a lot of resentment.
