Falling out of love

I’ve been married for 5 years and we have two kids 4yr (m) and 9month (f). Maybe there’s something wrong with me but is it normal to just fall out of love with your partner? Im 25 and got married when I was 20, super young. I definitely feel like I settled and missed out on so much. I love my kids but I just don’t feel attracted to my husband anymore and I don’t like being around him. He doesn’t have an ounce of romance in his body and every time I talk to him about my feelings he turns himself into the victim. I miss having a spark with someone.
