How I found out the guy I like has a daughter?

Me and this guy have been talking for about a while{2 months or so} been getting to know one another I’m starting to like him ..he seems to win me over cause he is so sweet and tender with me and very caring but I told him hes sweet and he said well I have a lot of love to give witch iam holding back…what does that mean?..when he said that?..I mean there is an age difference he is 29 and im 19 ..but the thing is that age if just a number and it doesnt matter to me.and he thinks that ass well..today we were talking about how many kids I would love to have and I told him 2 or 3 meaning twins lolz or triplets lolz and he was all like there is something that I need to tell you im all like o ok..and he was all like probably we havent even reached the topic .. Or I havent said it and im all like ok..and he was all like will talk about it tomorrow cause I really need to go..and im all like you got me all curious now..and he was all like I have a daughter witch she is the whole world to me ..she is 9 months old…and im all like ok…I couldnt say anything cause I was speechless..I known I been wanting to ask him if he had a child but I don’t know I never did ..so he was the one that brought it up ..and I ask him are you still with the baby mama and he was all like no..ill tell you tomorrow its a really long long story..and I stayed quiet..and he was all like do you have any question or anything you want to ask before we hang up that got you puzzled and speechless..and im all like will talk about it tomorrow and I stood quiet and he was all like I really really love talking to you..and I told him I really love talkin to you ass well and I told him to take care and will talk about it tomorrow the thing is it got me wondering how come he didnt tell me sooner?I mean his baby is 9 months probably he is still with the baby mom still..questions are just running wild any opinions Thank you so much for your time
