I don't think there is anyone else. And yes it is possible that she might be comparing me to a co-worker.
The reason I say of course her being older is that she is already done with her undergrad and masters and she already has a successful job.
And I'm 23 she just turned 30, we have been together for 6 1/2 years now and married for 1 1/2. Before us she was in a relationship for 2yrs and before that she was with someone else for 4 yrs.
The age difference does'nt seem to be a problem, the only problem that we had was when we first started dating, other people of course loved to talk about it. And some of her freinds have told her that im to young for her. Other than that I do not see that it is a problem between us. Just other people feel that they need to voice there opinions on the subject.
