Some girls love dating older guys b

Some girls love dating older guys because they feel as though guys their age are not mature enough & some guys like dating younger girls because the women their age are ready to settle down and they're not. What ever the reason is just make sure you have a connection other than Physical appearance because physical appearance can change quickly (Esp. in relationships with huge age gaps.)
One of the biggest challenges people with big age differences face are the generation differences. You both have to be willing to learn about and respect each others generation.
If your in an age gap relationship you may want to have a support group to help deal with some of the controversy that comes with dating someone from another generation. Support groups for age gap relationships will understand your relationship and will helps make things a lot easier.
Be confident with the choice you've made to date a younger or older partner. Don't think you have to convince everyone of your love. If thats who you love then you should never feel ashamed, try to hide it or need approval from a critic.
