Further to advice

Hello ladies I’m so confused. Me and my ex split back in 2017 at the age of 19/18! We don’t actually know why we split.. because we wanted to be together🤷🏻‍♀️. But his recently got back in contact with me we always come back to each other been that way since we split. I have a baby with someone else but I left him due to DV in my relationship. His also with someone but hasn’t been long, she’s the first relationship since we split.

Does it seem he has feelings still🤷🏻‍♀️. We are always running back to each other and arranging to meet... I’ve always loved him he was my childhood sweet heart and lost my virginity to him. We also previously was engaged and lived together so very hard for me not to always love him. Can I have any advice please.
