I broke up with my boyfriend but may still have feelings

Ok so I (she/they) have broken up with my boyfriend of 3 months (my first relationship ever) and I think I still kinda like him but the feeling is going away. I broke up with him because every time we hung out things were great but as soon as he left I felt full of regret I hated the feeling. Throughout the relationship I also wanted to break up with him and get a girlfriend. Mind you he was also my first kiss so I don’t know anything about being with a girl but wanna explore that side of me. What do I do?
