my boyfriends sister.

[love_linds]

me and my boyfriend hav ben going out for one year and six months.
im 15 and his younger sister is 14.
we use to be really good friends. w wold talk about everything spend a lot of time together. then one day we had this huge fued. because she was saying she loved a guy she had never even met. and i kindly told her that she is stupid and that its not true.
she ended up getting really mad at me. so we didnt talk fo months and months.
now during this time i got really jealous of her. i mean i didnt lik her because she was stupid, annnyoing, and immatuire.
and it turned into a "stalker" kind of thing.
i would contantly check her myspace, always wonder wat she was doing. but that because i wanted her to be miserable.
just about 4 weeks ago i fianlly apologized to her because i was tired of feeling uncomfortable around her.
now we are ok, sort of.
i still get this jealous feeling towards her even tho i want to her to be miserable with her life.

is this normal?
and i just hav no idea what to do!
any help???
:confused:

Jealousy is normal definatly, but you need to learn not to be jealous of her. As you have your own great stuff, you do not need to wish and see what another has.
