Dear oh dear....but this is not unusual this is just typical of the species we call men!! I have been with my unromantic partner for 20 years, in the first year, I got flowers, chocolates, taken out for a meal on birthdays valentines etc, then with each subsequent year, one treat was dropped, the last time I got flowers they were fake "'as they will last longer"' (at least I can see where he was coming from!). I have to heavily prompt him about my birthday, but at least he does buy me a card and tonight I asked him what he wanted for christmas, to which he has replied "peace on earth". Christmas discussions for him are out of bounds until at least the 23rd!!
He is not romantic, but at least he is supportive, reliable and I know that anytime I need him he will be there 100% for me, and yes I know he loves me.
As a lot of the others have said, you need to understand what is important to you. As the years go by in a relationship, the romantic side, altough important, takes a lessor role to the way a partner responds to the day to day dealings with life which can be far more stressful and I know I would far rather have a partner like mine than someone who may remember to bring me flowers or a card, but is not there for me when it really matters.
Hope my rambling reply has helped a bit, I have enjoyed reading the imformative and funny responses made by others on this thread!!
