Wedding invitation? - wedding invitation freeware

I've just been invited to a wedding of friends who I havent seen more than a year. I'm with a woman in the last 9 months and I wonder whether it is acceptable to take as my day, though not his name appear on the invitation? I will not ask to the party, because how could we not say and do not offend me too. Basically, it is permissible to set a deadline invited to a wedding?
