Fuck buddy issues

💍💕 • Mommy of one beautiful little girl and married to the love of my life.❤️
So recently my fuck buddy popped the question and was wondering if him and I could be more then just fuck buddies! I'm not the dating type! I noticed during our few last hook ups he would try and cuddle and get close to me, but I'm not the affectionate type of gal. How would I break it to him?
