what to do??

I’ve been talking to this guy for a while now on and off and we just recently started talking again. it was going well, he lives in another state but is planning to move back to where i live. we were talking about being together, meeting families, having kids, etc. but he told me he wants to have multiple baby mamas basically and multiple connections with people. my pervious relationship was similar to this and ended badly for me which i’ve expressed to him so he’s leaving it to me and i don’t know what to do. i really like him and honestly imagined a future with him but now i’m not sure.

any advice?
