Text: i've been with my girlfriend for four years and we have a beautiful little girl who was born in november of last year. we're not married but it's on our agenda for 2016/17. my daughter's name is caitlin: i chose the name. caitlin is one of my favorite female names: it can be caitlin, kaitlin, caitlyn, cathy, kate, katey, catherine, and more. it's a versatile name but i always liked caitlin. heather is another female name i really like, and that's my girlfriend's name. for what it's worth, my girlfriend wanted to name her robin after her father (robert). i won in the end.

prior to meeting my girlfriend, i was with a woman named catherine. before that, with a woman named caitlin, and before that i was with another caitlin. you might think "oh, it's your favorite name because all your girlfriends have been named this", but that isn't the case. if anything, i'm attracted to the name and when i meet someone with that name, i immediately connect. i've adored this name since i was a little kid.

my girlfriend didn't know anything about my ex-girlfriends but in casual conversation i talked a little bit about them this morning over breakfast. she wasn't amused, not one iota. if looks could kill, there'd be a crater where my house would be.
