Yeah hormones are a big part of that it will get better! For me it seems like my jealousy went away...me and my fiance get a long very well now and I know I don't have to worry about anything :)
Hormones change you!! Im not jealous, I get impatient! (Lol, it's one of my first symptoms) :-) The other day before my appointment, I ordered a pretzel which was supposed to take 4-5 mins... it took 20!! I said excuse me. The lady said did you want something else? I said NO, IF MY PRETZEL WASN'T READY I WAS GOING TO ASK YOU FOR A REFUND!! Lol, it gets better.. AFTER YOU HAVE THE BABY :-)
