dude if you were my boyfriend i would totally break up with you! why would you do something like that?!? shes your gf and this is a romanic holiday and you send stuff to another girl! i would consider that cheating wow this made me so angry how could you do something like that and betray your gf??!?!?!
I hope that it was just one of those elementary Barbie valentines and not something charming like flowers or chocolate, because otherwise, I'm sure your girlfriend would have lots of help taking you down :D
You should never do that it makes the girl feel upset or jealous just stick with getting your girlfriend stuff and not another girl even though you might be good friends but since you did anyways just clarify with your girlfriend that you are just friends and all that
Yes if it's ok with her and just a just a little chocolate , me and my bf give small chocolates to our friends and Neighbour it's no big deal just give her the most special Gift like flowers jewelry ect.
