Gina, ya feel bad cause no one (I hope) likes to make someone else feel bad. It's that mother installed guilt
Feeling guilty doesn't mean you DO like/love him, you just feel guilty. You're not attracted to him....period. Nothing he says or does will change that....that's the way it is....there really is no need for more conversations, and don't feel bad because you don't want a relationship. Personally, I wouldn't be answering emails, text messages, or the phone for him to throw more guilt my way. He can't morph into someone else....you weren't attracted then, you aren't now, and all the whining in the world isn't going to change it.
