Surprise, my wife apparently now has a relationship with a guy. Advice given me says "I need to work on my entanglement" because it doesn't feel okay for me to "share her". (Different topic, different post - check my profile history.)

I have a tremendous problem with that. I don't want to disentangle myself from my spouse, that's the whole point of a relationship! My wife asked whether me being a twin has any influence on this, which got me thinking.

As a twin, you have a fundamentally different experience of what it means for two people to be part of a whole. Most twins struggle when one of them gets their first boy/girlfriend.

It wouldn't surprise me if this was a huge factor in my feeling of loss, of diminishment.

Any twins out there able to share their experiences, thoughts?

Responses from non-twins are welcome as well - so long as they are respectful of not knowing what that's like.
