How do you deal with hurting someone else?

Emily

I’ve been seeing this guy for about 2 months. He made it clear from the beginning that he was VERY into me but my feelings just don’t match his. We talked about it last night in person and I feel terrible. He’s a really good guy. I’m 34 and this is the first time I’ve had to do this. I’ve always been the one getting rejected so I know how much it sucks. I think that’s a big part of why I’m struggling with it so much. I’ve been in his shoes. Any advice for feeling badly after breaking things off with someone?
