Confront him. And get your friends and his friends (like his best man) to back you up. But if he gave a friendly kiss on the cheek, then you shouldn't be worried ;)
Avoiding her in public and avoiding her husband in private.
Yes Cleopatra kissed her husband when she got married.
You simply join in.
No.
First, ask her if it was intentional or if it was him. Second, ask if she likes him - if she does, maybe you should get to know him better, too.
Yes, her husband, Ben Seewald.
Ok, so I'm trying to figure out what the question is here. You are in love with a guy who appears to be your neighbor's boyfriend or husband, and she is also in love with him, but now, after having kissed you passionately on New Year's Day/Eve, he gazes at you constantly which means either you are at his place constantly, or he is at yours, or perhaps you are both at the neighbor's house. Right?...and you giggle. Try a threesome.
I have no idea what "wrongly kissing your husband" means, the mind boggles. The mouth and its various parts heal very quickly. Saliva sees to that, Keep an eye on it but I think it should be OK.
They did. They played husband and wife in the movie Blow, and I believe Depp kissed her at her Hollywood sidewalk star unveiling. I'm not sure who was luckier.
No
Make out with him intensely.
Helping a neighbor is a reason for being late. Husband is ill would be a reason for being late.
