Can a relationship survive on JUST love, not “in love” ?

I love my husband but I’m not IN love with him. I’m not sure I ever was. We met when I was barely 20, I’m now almost 25. He is 28. I am attracted to him physically. He’s a great looking guy. He is a good person. But he doesn’t get my humor (this really bothers me) he isn’t clean, he is very sensitive. He is OVERLY sexual. He doesn’t “set my heart on fire” or “give me butterflies” ...he never did. The idea of sex with him doesn’t turn me on the way it used to. I always thought maybe if I buried these feelings away, it would be ok. There’s so much good in him, it outweighs the things that bother me, but when it comes down to it, I don’t think I’m in love, I’m just comfortable. He is in love with me and feels that fire for me, but I simply don’t share the feeling. Could I see him being a great life partner and father one day? Absolutely. But my heart tells me to go.

Has anyone else felt this way? What did you do.
