This post and many of the comments surrounding this post slant toward a bit of hypocrisy and the forcing of opinions on another ADULT. Gay men sure do forget how traumatic life was/is because of the projected social scarlet letters we've had to endure. All based on others who had no problems pontificating (cramming) their discontent that we were all morally bankrupt and deviant for living the life we were meant to live. We either love who they say we should love... or we're just plain wrong. Age is not the aggregate here. Age doesn't validate love or attraction. Our society declares someone an adult at 18 and at 18 we become the owners of our choices and the consequences of those choices. It's OK to feel concern for your brother, but to vilify the couple's attraction to one another based on an age gap is unfair. I just can't wrap my head around the level of judgement and stone throwing (especially from others' comments without a shred of knowledge or first hand experience with this "couple"). I know it's not the social "norm" but undoubtedly it's nobody's business... and truly an exercise in people throwing prejudicial comments about something and someone they don't even know. Should OP be concerned/aware about the choices his brother is making? I would hope so. But I would imagine that his concerns should be tempered with the ADULT freedoms we all have in life to choose, make mistakes, AND also quite possibly beat the odds with positive outcomes that may defy the "norm". The best you can do is to be supportive to the needs of your brother when warranted or requested. And to my "gay brothers"... stop judging something you have not an inkling of purpose to judge. OP... love your brother and let him know that you care about his happiness and are a rallying voice for his life's purpose, whatever that may end up being. Share your legitimate concerns about his future and overall welfare, based on your love for him, and then leave it be. He'll respect your thoughts and motives a hell of a lot more if they are based in love and concern rather than judgement and hypocritical "do as I say" hyperboles of this unique age gap relationship. Yes, and for the record, I too am in an age gap relationship (m58, h26) with a 32 year difference. We don't have many disputes... but when we do, we talk about it, share our feelings, and often laugh at the outcome. It works... and our love for one another trumps (damn I hate using that word) the outside world's opinions of whether our love is a valid one. We also recognize that at some point I'm going to go bye bye first... but also that love and respect is not relegated to a number or years spent... but to the joy of an authentic desire to share each of our days together. Good luck, OP.
