Of a 26 year old single man who hadn't had a real, (grownup?) relationship?
He has a good career with some unsociable shift patterns but the reason for him being single is not because of being too 'career focused'.
He has had two relationships of about a year each but hasn't had a relationship for over three years so those year long relationships were when he was relatively young.
His most recent 'relationship' was very casual but lasted two years. He didn't date anybody else in that time but not because of commitment to the other person, the opportunity just never arose.
He's never lived with a partner, nor overly had to think long term.
Would you assume he is in some way hugely flawed to have got to 26 without having a 'real' relationship.
Would you also be concerned that he would not be good in a relationship because of lack of practice almost?
