Is it normal to date someone who is 20 years younger than me while the mother is 2 years older than me?

She could be your daughter you know? You must know that she's still very young for you, she need to grow up first. If you marry a girl her age, you might end up marrying a little girl. Consider the differences, she may like things you don't even know, you may like things she may not even heard or saw in her entire life. Imagine, you were thirty when she was just a ten year old kid. You were twenty when she was just a newly born baby. She's still a child inside, I know that because I am only a year older than her. Talking about her mother, her mother may not like you because you are almost her age. You maybe a good man but that doesn't mean you can understand her daughter's feelings because you are too old for her. I am not saying dating a younger girl is bad. If you two like each othere then go for it. There is nothing wrong with being with someone you love, beside age doesn't matter, right?if she likes you too then its better.

Dating is supposed to be a mature thing to do. Mother's don't count.

If you two are equally attracted then go for it. but I learned from family that age does make a difference because you'll be 50 when she'll be 30 and when you guys get settled and have kids, will you still have the energy?

From experience...

Don't think its not normal.
A lot of people have partners that are a lot older or younger.

If the realtionship is right then I don't see why it should be a problem.
Others may disagree with that, but when its love its love.
It's hard to imagine I would do that... but becuase of the situations I have grown up in
I know there is nothing wrong with it.

Do what feels right and respect the girl :)

Please answer my sexuality question :)

Can you blame her mother? Of course her mother would not like it. There would be something very wrong if her mother did NOT have a problem with it. What is wrong with dating someone closer to your own age and has more in common with where you are at in your life? You have nothing in common with a 20 year old, and if you do, there's something else wrong. She barely out of high school. She isn't even done growing yet. She can't even legally drink.
As a 20 year old myself, I would smack one of my girlfriends if she wanted to be with a 40 year old man. You will never have anything in common with her and her friends.

Is not hugely common... but yes its normal...
Its a hard subject... a lot of people would object to it.
My dad was 23 years older than my mum and they started the realtionship when she was 21. They were madley deeply in love and it really worked!
He was well liked by my mums dad and the rest of the family.

If its love it will work out, age doesn't always matter. It depends on the foundations of the relationship and how you work together.

I'm 26 I don't think I could date someone who is 46 . Would you date some one who would be nearly 70 when you are the age you are now? What's wrong with women closer to your age?

I find it hard to relate to many 20 year old girls at 31. I'm sure that's exacerbated at 40 thus why you are asking to begin with... While I wouldn't at that age, if she's fine with it, and you are as well then do what you want. It really depends on the girl and where she's at in life. I can't say that I've met a ton of emotionally mature, responsible adults that are 20 or younger. Some start to get there around 22 to 25, but are still figuring things out.

i say be a man and take what you want
if the girl likes you and you like her I don't see a reason why yous wouldn't go for it just because it makes some people puke.

These girls barely have life experience and you're exploiting that weakness for your own sick pleasure. It's not wrong, afterall you like what you like. It's just really f***in inappropriate.

They CAN look after themselves, sure. It's NOT breaking any law. But come on. You're behaving like a child. You know what the ramifications are for choosing partners who could be your daughters. You're a grown man. Now man up and deal with the consequences. If you can't handle it, go for women in your neck of the woods.
