A: Guys don't like super skinny (skinny model) girls... they feel like throwing a pizza to them!! You have to look healthy guys need to grab some ass you know? Healthy bodies are better than skinny model girls. :)
A: No, it's better if you tell her that in person ...if she's travelling for long...then do it...but if she's coming back soon you should wait so you can see her reaction because if you do it by phone anything could ruin that moment and maybe you could never have that moment back.
A: It depends on the time you both spent together but mostly they call because they're still used to whatever you guys used to do when you were together...it takes some time to forget all of it.
A: If you're in love with this girl you shouldn't be there anymore, she's being immature and doesn't even know what she wants, trust me...I've done it. You want to keep the guy there just in case but let me tell you it's not gonna end up nicely for you. Eventually she'll end up dumping you.
