Hey! JMs' suggestion is right. Just get ready for "bothhands" first. If Y really becomes a very nice guy (even I guess the chanceis minimal), that's great. If otherwise, you have to get well prepare to"escape". Is there closed friend you can stay with for a short while?Pack a bag of baby stuffs first (just for emergency). You know, you reallydon't know what the next step of Y is... why don't you get yourself prepared?
Remember, you must protect your kid from "dangerous"all the times.
Anyway, enjoy your motherhood!
