How to rekindle a relationship

I have known my boyfriend for 3 years and have been living together for a year and a half, but lately the relatio ship has being going south. I use to have a squeaky clean home, dinner ready, i would up keep myself, be very happy to see him, and do little romantic details. After a while we started falling into a routine and when I noticed this I would let him know that we needed to be more spontaneous. Yet, it never happened, I would arrange dates a the park or small details for him but he would said no I rather watch my soccer or never listened to what I had been asking for. Just a flower, or a card or "honey I'll cook dinner tonight." But nothing. I stopped doing all these things for him and his kisses dont bring butterflies to me anymore. I just need advice on how to rekindle. Is it possible to fall out of love?
