I've been with my boyfriend for 2.5 years. Everything is great and I recently started feeling like I realllllly want kids, I've never felt it so strongly before. However, we have a 15 year age gap (25F, 40M). Initially I was so excited about telling him but then I started thinking about our long term future and elder years..

Which is where I feel really unsure about it because I've heard women tell stories about how they become caretaker once he gets older, he could have a much lower sex drive when I still have a somewhat healthy one, and other concerns that come with big age differences such as being at different stages of your lives. I thought about our kids and what it would be like for them having parents with this age gap. It also made me sad thinking about not being with him and growing old together, it sounds kinda cheesy but I love the idea of growing old together and drying together (sorry the Notebook must have got me). It breaks my heart to think of my elder woman self as a widow for a long time. If it was 5 years I wouldn't think twice about it. But 15 years... that's not insignificant. Of course, whoever you marry, you never know what could happen, but I'm thinking in terms of the odds.

The good thing is, he is really healthy, eats well, has always been into holistic health - so he takes vitamins and supplements, exercises, etc. And he does look young for 40. People compliment him for it all the time. So that does give me some comfort. But still.

What do you suggest is the best course of action? I don't want to bring up kids, only to follow it with "I'm worried about the age difference." But I also feel like talking to him about it will help me to decide. Also, he hasn't specifically said that he wants kids, but I think he'd be open to it based on comments he's made in the past. However, he might not want them at all, in which case, I wouldn't even need to worry about bringing up the age difference because the kids things would be an irreconcilable difference between us, which would probably lead to breaking up.

Are there any women here in LTR/marriages with men of a significant age gap? Do you have any concerns? Have there been issues due to the age difference? And how should I move forward because I've been DYING to tell him I want a baby but also don't want to crush him if I eventually realize the age difference is too much for me. I'm assuming that I just need to decide 100% before mentioning it to him, but this is really really hard. Any insight or suggestion would be greatly appreciated :)
