Ex has a new gf but said he’ll always love me

My ex and I broke up in January. We were in each other’s lives for 10 years. Since we were in 8th grade. We got married 3 years ago and have a daughter together but it ended up not working out. We didn’t help each other at our lowest points. He always had depression and after my daughter, I had severe postpartum. It turned us against each other and we never got those issues fixed during our marriage. We still love each other but he has moved on and I respect that. But today he made it clear for the first time since he started dating this girl that he “loves me and always will” and he wants us to always be friends. Is this okay or would I be overstepping since he’s with someone else? I feel like he rushed into a relationship. I’m still hurting and healing. I just don’t know how to handle the situation
