I am yet another story of 1st marriage - fancy big wedding, marriage lasted 6 months... 2nd marriage got married on the Vegas strip just the two of us and look back on the wedding as the most intimate thing we could have done.
As far as becoming Catholic to have the big wedding to make the occasion more special, honey you've already thrown tradition out the window with the baby before marriage, why try and save it now? Catholics may not use birth control, but they certainly believe in exercising abstinence before marriage. I hate to tell ya, but as the mother of two kids, if you never had the money to get married before, it's not going to be easier financially after the baby comes!
As everybody has said he can't call in sick for those days now. Doesn't he have any PTO days to use? Has he had excessive call-ins already? It's so odd his employer wouldn't be more sympathetic to the fact his baby is about to be born if he has been such an exemplary employee. I think now he'll just have to be an unexcused absence, take the suspension, and use that time to hunt for a new job!
Good luck on Thursday and congratulations!
