How should I react to this co-worker/friend? She playfully says "I love you" every time we work together.?

You can make a joke of it..like you have said, or say "I love me too"..anything like that

Or if it is really bothering you, I would suggest you take her aside and nicely say you like joking around but you really don't like her saying she loves you...maybe save that for her boyfriend or her father..LOL

It depends. Do you want it to stop? Do you find it inappropriate behavior for work (as I do)? It you want it to stop (as I would strongly suggest you should), do not chuckle or smile or remind her of the BF. Tell her, in a serious tone, that while you get along with her, you find what she is doing inappropriate and you ask that it stop, because this is a workplace and that is not a way to interact with a coworker. If you like your job and want to stay employed, you don't do stuff like that in a place of business. She is young and not too bright, so you need to be very direct. If you chuckle and smile, it completely changes the tone of what you say, and she won't listen. Frankly, she sounds annoying.

It is not your business how anyone else might take what she does, though her actions could well get her into trouble. The bottom line is that, for people who are confused, emotionally immature, and have BFs or GFs, the best thing you can do is run like crazy in the opposite direction. These people are nothing but a boatload of trouble. You don't want HER getting YOU in trouble, either. Keep the focus on business, and do the mature thing and squelch the nonsense.

Depends on how old you are. You don't want to hurt her spirits forever. I know what your saying though. I don't use "love" very loosely.

If you are sure about not liking her then say something like "Oh have you and your b/f seen this movie"... or so have you and your b/f ever talked about getting married... take it easy on that one though she may think its an invite if shes "little".

She needs to be stopped now though because it will get you into trouble weather her b/f finds out or you get a woman and she continues to do so. I hope I've helped! Good Luck!

you could laugh and say jokingly back "i love you too"

or smile is fine.

and catch her off guard once or twice and point out the boyfriend but in a joking way.

Give her some xanax and a few shots of 151.

kindly remind her of her boyfriend with a smile

lol... it sounds like she just wants to be friends, sometimes when girls say "i love you" they just mean.... your funny or your cool or i love hanging out with you.... especially immature girls.... lol trust me i know... i am one.... it sounds like she just wants to be your friend and as for her boyfriend.... dont remind her she has one... she knows
