You can get past those feelings with a different way of seeing the situation. It obviously is easier when you accept the ow is in his life and he is in your past. Yea you struggle, feel bitter etc but it was a long time ago now. You should concentrate on you and your life, free from a cheat and all the deception, lies, false guilt and lack of trust that a cheat heaps upon you.

I know what you mean about hoping their relationship is doomed, but that's a negative thought as well. Think positive, be positive and feel better for it

I think it's important to see that this wasn't an either/or situation: his choice wasn't her versus you.

For some reason you weren't right for him. I'm not saying that with judgement; he might have been a giant jerk and she was more temperamentally suited to his jerkness. Or he was wonderful and she was more suited to his wonderfulness. Whatever. But whatever it was about him, it did not mesh with you.

I think you just have to find the guy who's perfect for you.

I had a similar situation, but my life is so busy that I don't even think about them. Make your life full and happy and it will cease to be an issue. Focus on your goals. Your kids will always love you no matter what. Be grateful that your ex and his wife are good to them. It's hard to be the one who is left, but your path obviously is going in a different direction. Wonderful things are in your future if you let go and move forward!

7 years is nothing, it could be 7 years of hell behind the scenes. "Lasting" is much longer than 7 years, it's a matter of perspective.

The problem here is you're focusing on them and that relationship instead of you and your relationships. It's always going to look that way and there will never be anyway to ever change it, if that's the way you're looking at it.

Instead of looking over there, look over here, at your life, in your area.
