<human>: I have my own concerns and reservations obviously, or I wouldn't be asking this question, but I need some outside prospective.  I female (26) dating a male (47) for going on 9 months. I met him online- I messaged him first for what it's worth- and against the better odds we ended up hitting it off. I normally date men around my own age. And he has only dated women within a decade of his. So this is new for both of us. I think that's what I was looking for when I contacted him in the first place.
  I have never had a goal of marriage or kids. And he can take it or leave it as well. He tells me he loves me and is happy with the idea of being with me long term if I want to. I have expressed reservations and he has expressed his own regarding the age difference. But I can't help but feel like I'm getting comfortable with him. And I could totally see myself commiting to him long term, except for the nagging fears that I have.

 So far the postives:
* I actually like this guy: smart, cares about my feelings, great with kids/animals/older folks, spiritual.
* Has his life setup - Homeowner, good job, financially secure.
* Things are good in bed.

Negatives:
* Potential future health problems/caring for an aging spouse much sooner.
* Societal perceptions about us.
* I'm not super attracted to him physically- but this isn't a diehard negative as I've had this problem in the past with boyfriends and mental attraction is much more important to me..

Can anyone help me to flesh this out a little bit. What do you think about relationships with large age gaps? Have you been in one and what went right/wrong? What else should I be focusing on here?

Can you condense the text into three sentences or less?
