I guess to me, being happy in any relationship, is to be able to just be there for the person. In my case, we are just both very simple people. Just being there for him, listening to him, talking to him, hugging him or just simply sending him a sms to show that i care, will make him feel happy and safe. same goes for me.of cos there are times where we get bored too, so we try to do different things like playing board games, going for walks after dinner, cooking meals ( we seldom cook), go to places that we don't usually go and etc. i think it is also to try to do different things, so that life is spiced up and not routine. so far, i know that just being there for him, letting him know that you love him and care for him, is the very basic in order for couples to be happy for a whole lifetime. do not let them think or discover that you have taken the other party for granted.
