Ok..so my ex broke it off with me after 7 yrs of being together...his aunts still call occasionally to see how im doing and whatnot..but when we broke up, i quit my job (i worked for their family business) but before i left i told his dad that i was disgusted with him, his wife and his son (the ex) because well...the ex was seeing someone else and they all knew and didnt do or say anything about it...and i was very close to the whole family..anyways...he has a younger sister who is turning 7 soon..ive been in her life all along..my question..although the ex has a new gf and i pretty much have already washed my hands clean of him and his parents..can i send her a birthday card telling her that i still love her? (the last time i saw her was the day before i quit my job and she told me that she doesnt understand why im not around anymore but she hates her brother for getting a new girl because she never gets to see me anymore.)
