Meeting boyfriends baby mama😟

So I’m meeting my boyfriends baby mama today. He said she’s been wanting to meet me since our daughters have been wanting a sleepover. He’s very nervous about the whole thing cause she was upset about me being around her child at first now he’s saying she wants to be friends. I would love to get along because fighting doesn’t help/ solve anything. He’s daughter is 12 and mine is 10. Our relationship is serious and I know I would have to meet her at some point.

Any tips/advice?? Has anyone ever been in this type of situation before?

P.S. He also told me that she still has feelings for him and said she tried to kiss him about a year ago in front of her bf (weird).
