Spiritually motivated by only a girl?

I’m at my best when I’m in love with a girl. I go through obstacles and I’m productive like no other. However, when I fall out of love I become a couch potato. I need on singular girl too go towards or it doesn’t feel worth it.

I have other goals too like helping the needy and becoming best version of myself, but they don’t motivate me at all spiritually, which I feel guilty about about.
