Question..

Girls .. am I the only one who gets a little unattached from their boyfriend when PMS'ing or on their period? I Just feel like I need space, i don't even want to be touched and constantly feel bothered. I hate it because he thinks he did something wrong and keeps apologizing and doesn't understand that it's not his fault, it's just my roller coaster of emotions.. am I the only one? What's your experience with that time of the month?
