I think Beatrice is absolutely right. It's something I wanted to say to you for a while now. The fact that you are still counting their vacations shows that you are still focusing too much on what your ex is doing. The only person you are hurting by doing this is yourself. You need to step back from all this and keep your focus elsewhere or else you are just going to drive yourself crazy.
I know it's hard. My ex and his girlfriend have gone on numerous vacations too. At first I used to know when and where they went, but I stopped checking up on their life a long time ago. I have no idea what they do with their life anymore, and I am more at peace now that I don't focus on them. It is a gift I gave myself. You deserve this gift too.
