confusion

hey guys,

i’ve been talking to this dude for almost a month. yesterday i asked him what he wanted from me(jokingly). homie said i’m an investment to him. i honestly do not know how to interpret it because he said that he puts time, effort and that’s why he views me as that. he’s 35, i’m 21. i’m lowkey feeling him but i do not know how to interpret what he’s said to me. can someone help?
