Does anyone know of a mental disorder that makes you a complete jerk to your girlfriend... crazy question I know but seriously he was on meds before I came along and was a happier person... His doctor thought he might be Bipolar... I believe there is something going on... just not sure its bipolar.. This is not all the time but a lot of the time... His Dad says he has always been a moody boy... And he treated his girlfriend of 2 years the same way... Anyway could say a lot more but just wanted someone's take on this... He is20 and I'm 19... Even his friends say he is a mean guy... He has never hit me but doesn't talk the nicest... sometimes.I know his mom is on meds and she said that she can be very mean if not on them... Don't know... I just know if meds help great if not got to get out... We are engaged... been dating 10 months... He has not been on any medicine since I've known him... Thanks for any opinions... I do remember he told me when we first went out that he was a depressed person and I thought he was kidding but... I also know a symptom of depression in men is anger... but anyway "Thanks" for any opinions!!
