Set his ass loose because he obviously doesnt trust you. Tell me what's a good stable relationship without trust?.....Nothing.
You cant base the way a guy feels about you off of a txt.
Simply ignore them and think to yourself that you dont need to stoop to their level of stupidity.
If you feel in your heart that you should do it than do it. But personally i would make him wait for it. He'll be wanting your lips more and more everyday!
They are bored with their own lives and need something interesting to do.
No because your just joking. And if your friend took offense then you shouldn't do it again but make sure she/he knows your just playing around.
