Tell me what you think?

My longtime bf and I broke up a few months ago, I met a guys shortly after and we recently became a couple a month ago. Truth is I still love my ex. Am I wrong for dating the new guy, he is so sweet and caring, and everything my ex was not a real man, but he's not very cute, by ex was so fine, ppl always complimented us on how great we looked together. I know I am shallow bc beauty is only skin deep and my new bf is beautiful on the inside….do looks matter that much
