Nowadays age doesnt matter. As long as you both know what you guys are doing.
There are 3 basic ingredients of a happy relationship.
TRUST- Trust your partnet and remove Jealousy and things follow accordingly.
Contentment- Make sure to be contented with what you have and dont be a fault finder. This correlates with Trust. (You know what I mean)
Companionship- This mean that whatever it is that you guys will incounter as long as you treat each other with LOVE and RESPECT then everything will follow.
I dunno if this makes sense to y'all but it helps me alot but then my partner still left me hahahahahahaha....
