I want to date and have fun but I also have a baby.

Am I wrong for wanting to date and go out with friends? I am a new mom and my baby’s father left me. We are not together one bit. I can’t help but to want to go out and have fun. I’ve only ever had sex with 2 people. I see him enjoying himself and there’s a part of me that has some jealousy and resentment. I am always a mom first she is my top priority. I am ebf so I haven’t been able to enjoy alcohol. Not that I need it to have fun but I miss it. I want to explore what it’s like to date. I’ve only been in 2 relationships and my second having gotten pregnant. Is it wrong for me to want to have sex with a new partner? Obviously I will not because it poses risk to my baby. I just hope my life will resume a little bit? I feel guilty for having these feelings. I feel selfish. Also I keep hooking up with my child’s father. He’s been with other women and we don’t have feelings for each other it’s just easy for me. He swears he wears protection and I’ve been tested. (Yearly gyno appt) Please no judgment.
