My dude (and I prefer that to partner), is a boy and is my friend, which makes him my boyfriend. My dude is the one I love and I love him like a husband like his wife and I will perhaps hate him as a wife hates her husband. Alex isn't my second half, and I'm not either his second half as we are two different entities, he's not my possession and I'm not his, I won't say that I wouldn't care that he had sex with other people than myself (because he did and so did I) but as long as the love and respect we have toward one another bring us back to one another diseases free I'm his lover and he is mine.
He's my partner in business, alongside with other, but he's not my partner in life as we share more than a single bank account together. He's not my husband and even if we were married it wouldn't changed anything in my definition, as to me marriage means NOTHING at all, I would marry him for the sake of governmental perks, but I don't see marriage as the ultimate seal of our affection to one another (being with him everyday and knowing that we love each other almost equally is our seal). He already has a very expensive ring to its finger and I gave it to him for his 23rd bday to mark our 3 years together. It wasn't a sign of possession because when he decide to go fuck with somebody else (which rarely happens without me being present) he can definitely remove it as I would remove mine too.
Alex is my dude, and when I refer to him as my dude, I really don't care what other think, but if they want details, they just can ask and if I feel replying I would, but most of the time (although I'm very open in this board) I do not give much details about us in real life... I let people speculate since that's what they love to do and it entertains them.
In real life, you wouldn't know that we are a couple, good and very closed friend YES, but nobody would ever know that my dick has so many time visited his holes
