If you're bored, say so. If you want to be amused, entertained, say so. Kung gusto mong kinikilig ka parati, say so. But if you look for kilig moments and are bored because matagal na kayo - then don't ask for a mature relationship because sounds to me that you yourself are not mature yet. Being mature is realizing that a real and true relationship is not made up of pa-cute, cheesy, lovey dovey, pink hearts, flowers, chocolates, stuffed bunnies and surprises. Its enjoying each moment with the person you love, even though the moment itself is so mundane, so ordinary, so unromantic. And do something to keep the love and the romance alive - wag mong intayin parati na yung partner mo ang gagawa ng paraan. Dapat ikaw din - for yourself and for your partner. Ang relationship is a two way thing - hindi pwedeng isang party lang nanggagaling ang effort to keep the flames of love, lust, passion, interest, excitement, fun, alive. Do you know the reason why you're bored? What can you do about it, and are you doing it?
Why do we expect other people/our better halves/our partners/husband/bf-gf to make us happy? Why can't we be independently happy? If he can't entertain me, why can't I entertain myself? If he can't make my day, why don't I do something for myself?
If you realize at the end of the day that you don't need to be with him/her to keep you sane, alive, happy, enjoying life, then you're not for each other. Be with someone that you NEED to be with, just because.
