One of my close friends is 25 and her boyfriend has just turned 40. They were 21 and 36 when they got together. Now don't get me wrong, he's an absolutely lovely bloke and they are very happy, I was a bit wary at first hearing about the age gap but he's been around for so long and they are happy so I just got used to it and kind of forgot about it. I've met him lots of times and he doesn't seem his age and he does look younger, he's a very fun character. However she's just announced they are expecting a baby this year and I feel horrible for feeling this way, but I'm a little concerned. They are both so happy as are their family's.. but I'm just worried that it may not be noticeable now but what happens when she's 35 and he's 50.. they'll have a 10 year old and they want more kids so likely younger children too and I fear the age gap will really become noticeable then. I know it's not my place and my concerns won't change anything.. she's pregnant, engaged and in love. I just really fear for when his age catches up with him... AIBU?
