Hey Suzanne,
I answered last time, I've just read it back and it was fairly crap! Soz!
As I said before I have finished with my other half and it's driving me mad!
I would suggest that you ask him if he would be prepared to have counselling with you. I have always found this very helpful, it's a bit like having a referee!
If not, I would suggest when you speak to him get him to tell you what he heard before he answers. This can be very interesting and it may help you both to understand what you are trying to say.
I would ask him if he understands what you are upset about and how he thinks you feel about it. I am assuming the emotion that comes to the fore when he is talking to his ex is jealousy, is this rational? Has he been unfaithful to you? If not, then you need to change how you deal with the jealousy as this is your problem, not his.
I hope I don't sound as if I am preaching and I also know that when emotions are running high it is very difficult to be rational.
I am currently fighting the urge to call my ex. Just for a drink you understand (not that I'm trying to convince myself!). I am not going to.
I will discuss it with my counsellor and see what conclusion we come to!
Maybe you could have a break for a week and see how you both feel again then.
I wish you all the best and lots of luck.
BB xx
