Yes I agree with that - I don't think my wife's BF is an ex but she did stop seeing him for a while and then went back as she just couldn't resist being with him
But you would like to see her hook up with ex-BFs and like that she is in contact with them while they would clearly like to see her and rekindle previous relationships? I think that is hot
Mine would be when we met her BF in the local pub and they flirted openly in front of neighbours and friends and then went to the bathroom together returning after about 10 minutes....
