Lifelong friends

Hey ya'll! How are you guys doing today? I've been to a Christmas party tonight at an old friend of mine's house. We have been friends for most of my life. He and I became friends when I was in the 3rd grade. He is very special to me. I love him and would do anything for him. His wife is special to me too. She is great, very understanding and tolerant of our relationship. We do not have any romantic feelings for each other, and we never have.

There were a few people there tonight that I didn't know and I didn't realize the strange looks they kept giving to us. We were sitting on the couch. Sporadically, I would lay my head on his shoulder. He had his hand on my thigh. At some points, he would hold my hand, or lean over and kiss the top of my head. He had his arm around me when I got cold. Finally, one of the women I didn't know well turned to his wife. She had a WTF look on her face. Wifey started laughing and said "Oh, that's just them. They've always been very close. They've known each other since they were tiny." When I got there and when I went to leave, he kissed me and told me he loved me, as he hugged me bye.

This leads me to ask, do you have friends of the opposite sex? If so, are you that close? Do your significant others have any problems with this? Do you think this is wrong?

Talk to me soon, I hope you're having a good Saturday night.
