Okay, so he was pretty much AWOL ('absent without leave/permission'), once you BOTH sat down at the reception. The majority of the time, in other words, he was gone.
AND it seems by your description... he did not tell you where he was going (even if to talk to friends/the new couple), and he just left... then he came back told you to get food then left again. Then comes back after 1 hour... and did not say WHERE he went or what he was doing. Right? Then, then your CAR was gone... which you found out accidently. AND you were with your baby.
So then, you left with the car, when he came back, at that instant. Since then he has NOT shown ANY indication of where he is... or anything.
1) Did he call you?
2) At the wedding... how come you didn't just ASK him why he was coming and going so often and for so long...???? That is what most couples do... even if married or not. It is just courtesy to say something.
3) WHY was the car gone, when you discovered that by accident when you went to get diapers from the car? DID you ask him, WHY the car AND him was gone???
4) It is usual, at a social function, that people mingle. Even couples. You do NOT have to sit at the table idle. BUT you said you didn't know anyone there besides the bride/groom... AND you were also with your baby. SO.... then naturally, a Mom, would just be sitting at the table... at a social gathering. That is normal.
* BUT... MOST couples... will tell each other, head's up, on what the heck they are doing or WHY they have been gone so long and FREQUENTLY.... sporadically. BUT, it is also the choice of the other Spouse to ASK "where" they are going... even if just for curiosity. AND you BOTH have a baby, which was stuck with you... at the table. AND at a social gathering/wedding reception.
So, regardless, I think your Husband... was TOTALLY in error of his behavior... and rude, to you/your baby. BECAUSE, to me, he was acting sort of "weird" and not telling you anything. Just taking off and disappearing sporadically for various lengths of time... AND NOT TELLING YOU ANYTHING, NOR WHERE THE CAR WAS AND WHY HE LEFT WITH THE CAR... SECRETLY, and did not tell you he left the premises. Meanwhile, you are just sitting there.
NOW, your Husband is MISSING. Have you called the POLICE???? Filed a missing persons report???
Checked the hospitals???
Aren't you worried? Have you told ANYONE he is MISSING????
AND he has NOT called you? HAVE YOU TRIED TO CALL HIM ON HIS CELL PHONE??? At all?????
You need to tell the Police.... NOW.
Is this your Husband's "typical" behavior??? Or not?
have you called anyone at the wedding/the new bride or groom or anyone who was at the party and might have seen your Husband????
If it were me... I would be PISSED for how he behaved at the reception... but I would now be REAL worried, about where the heck he is and IF he is safe and alive... or what???
He has been gone a LONNNNNNGGGG time.
YOU need to find out and call the police.
Next, IF you find him and IF he returns home... (and he is fine)... I WOULD BE TOTALLY PISSED OFF ROYAL! AND you need to tell him BLUNTLY... that he pretty much abandoned you and your baby.... and this is NOT NOT NOT acceptable... AND he better damn well make it up to you, or else.
BUT you really need to find him. Has he reported to WORK? Does he work? CALL HIS BOSS. Think smart and do something.
good luck,
Susan
