my girlfriend keeps liking pictures and statuses of my friend, should i be worried?

Nope not to much it is over the line in my books but I am somewhat a jealous type so do wait for more answers but what I would do is say in a simple modest way you don;t feel comfortable with her saying things like that to your friends, you're friend told you about it ;)

Good luck oh and think of it how has she been treating you lately?

Well it sounds to me, that she is a big flirt. I would tell her how you feel, communication is one of the key things in keeping a relationship in tact. If she gets angry or defensive then that means she knows she was in the wrong. Sounds, to me like this could escalate to her cheating on you, so I would be careful of that. I was express to her my concerns and try to have a civilized conversation with her. She sounds like she has no respect for you, and in a relationship you have to respect one and another. I mean, there was nothing wrong in her committing, or liking said friends pictures, but she had no reason to call him "Handsome." Not just that, after that when your friend committed and said, "your boyfriend is more," and she said, " no you are," it just sounds to me, like she doesn't really care about your feelings. Then again she could just be trying to make you jealous. This, is why I would confront her about it and tell her how you feel.

Hope this helped!

Not cool. I would never do that if I had a boyfriend.

Like even if she thinks it, she doesn't need to say it, especially when your friend replied in that great way (props to him)...

If she's saying that stuff online where you can see it, who knows what she's doing/saying when you're not around?

Watch out. I would talk to her, and if she gets really defensive instead of just being like "sorry, didn't know that bothered you, I won't do that anymore" or something of the sort, then maybe you two shouldn't be in a relationship...

Personally, I think thats disrespectful of her. Its ok to like your friend's pictures or statuses but to actually say "you're handsome" and especially when your friend replied in the way he did. You seem mature and its cool that you're not blowing up right away but bringing this up to her isn't about jealousy, its about respect. How would she feel if you commented on her bff's pictures like "omg you're so hot" ? Talk to her about it! Hope I helped :)

Well get some vengeance pal, find hot friends of hers and start commenting and liking i'll bet she'll be real angry over that

She sounds like a jerk cheating on you on the net seriously?? Break up with her answer mine??
