That's a great topic to explore in therapy, definitely a biggy worth multiple sessions or touching on and returning to several times. I know it doesn't help your feelings of jealousy now, but maybe just in pointing to this possible direction in therapy, it might help to know maybe you can work through some of your anxiety about this.

I don't like to fly either, and am scared, but I just grit my teeth and do it, because I know otherwise I would severely constrain my life. Do you have one of those credit cards where you accumulate airline mileage? That can really help the miles add up quickly. Not all destinations require you to fly either. You could do a long driving trip. Or train. There are delightful train trips through the Canadian Rockies. I took a summer trip there a long time ago, by car, and it was wonderful. We went to Jasper and Banff and saw gorgeous scenery and hiked. If you are not into strenuous mountain hiking, there are many flat and scenic walks too.

Hang in there, Rainbow. You still have a lot of life in front of you. And Happy Anniversary.
