Though I’m not currently in a relationship, I do understand that keeping the spark alive is tough if you are not speaking the same love language or at least acknowledging that your partner speaks a different one.
A few months ago I took a test to reveal which was my primary love language. Not surprisingly, Acts of Service + Physical Touch tied for first place with me.

My friend Diane at Elevate Love suggests:
Do a “Start, Stop & Continue” exercise with your partner, by asking each other these three questions:
START: Are there things that I can start doing that would make you feel more loved?
STOP: Are there things that I do that make you feel rejected or unloved?
CONTINUE: What things that I currently do make you feel loved?
