Should I settle for this man?

I am a 29 year old professional who feels my biological clock may be ticking. I don't love this man, but he loves me and does everything for me. He'd make a great husband, however I am not physically attracted to him and we are almost always platonic even tho we are bf/gf. My work is busy and I may not meet anyone, plus I suck at dating so I feel like I should settle. Can someone who had experience give me some advice? Thanks!
