Feeling bad for not acknowledging his feelings in the breakup

I ended my 3 month-situationship with a guy recently, and have been feeling so down. The feeling of suddenly being silent is extremely painful and I like him a lot. And I have also had such bad conscience towards him since he got really sad, showing that it meant a lot to him, and telling me a lot of nice things afterwards about how great I am (but 100 % respected the descision). I almost havent responded to this because I was too sad at that time.

Now I feel bad that I was so focused on myself telling him that we couldnt continue (because I wanted more and he didnt), that I completely forgot his feelings of actually being dumped.

Anyone else experienced the same? Am I being TOO empathic here?? Or how do I cope with these feelings?
