It can mean this, however in most cases, if you say "I want to 'be' with you" means you want a relationship. In most cases "I want you" means you wish to engage in an intimate situation.
Talk to her about your guys relationship and tell her how u feel
This is what i think i would do if i was in that situation and was the girl. I would ignore you, say bad things, hang out with other guys, and all that fake, mean stuff.
A guy grabs a girl's waist to tell the girl that he really likes her, wants to hold her close to him and never let go
if she's a gay girl, and by gay you mean homosexual, then changes are she doesn't like any guys.
no
if you are interested in a girl who is in a relationship with someone else, jus talk to her all the time, and when her boyfriend does somthing to make her mad, tell her that she deserves better than that, and that you hate it when guys do that, you know, to make her feel better.
just forget about the relationship you had with him before, he's not worth it >_
Tell them!
when they ask a girl out
Only if the guy is willing to tell her about his y relationship.
tell her that you love her
Not on your first date. If you get in a relationship, then tell her :)
