Mixed feelings

First off, would love to have a second child. My first will be 4 yo shortly. I'm married to a great man (not my first child's father) and he would love a baby as well. I'm super excited and emotional thinking about having baby #2 but also feel so much guilt about not being excited for my first born. It wasn't planned an I was in an abusive relationship, i was scared and young and honestly believed I couldn't be happy or excited so I never let myself. Of course all those feelings changed after I gave birth but I regret not letting myself be happy and excited at that time and feel guilt over being excited now. 😔anyone else went throug this?
