Friends with benefits

My bestfriend and i have been friends for a little over 5 years now, and about 2 years ago we decided that we were gonna be fwb (it’s been on and off). I’ve always had mad feelings for him but i didn’t tell him until recently how i felt about him so he took it pretty well when i told him and everything was good with us... So two days ago out of the blue he just starts saying he misses me and wants to see me and shit i wanna hear but he’s never told me he loved me well we got on the subject and he told me that he did love me and that he wanted to us to just “ be there “ for each other and see where the relationship or whatever it is goes but now it’s just like he doesn’t care anymore... he was supposed to come stay the night with me two days ago also and i still haven’t seen him or anything like that and we usually text each other everyday and now we don’t so like what would you do if you were in the situation bc i honestly don’t know right now !!!! i’m 19 and i have a daughter which isn’t his but i don’t feel like that could be the case bc he came around while i was pregnant with her so like i just don’t get how he can just change within 2 days 🙄 HELP I NEED OPINIONS ASAP
