Would you be suspicious

If your fiancé takes your 2 year old with him were he he goes a lot ( not that part ) and he says he’s going to help his aunt out almost everyday and now out of no we’re this is the second time my 2 year old says dad I want you to go home now I want to go with you. I said is he trying to tell me something what have you been doing and he laughed and said idk but he would be the one to snitch on me or something so I asked my son if dad had another home and he said no and laughed but I’m still suspicious why all of a sudden he’s telling him to go home when we been living together way before he was born

Edit * I just moved to South Carolina with him 5 months ago this is were he was born and raised so I only have known her for 5 months and she does call him everyday to do stuff which annoys the hell out of me and I got tired of him not being home with me and my kids so he started to take our oldest with him but it’s just odd for our son to say that ...
