Most Helpful Guy
Like i always say... guys won't show you what you need of interest unless you show them the same... maybe you don't show him the same interest he shows you
Most Helpful Girl
There's no need to contact him. Masculine energy guys prefer he be the one to initiate explicit things. What you need to do is just enjoy yourself and be a joy to be around by being your self respecting self and being appreciative of what good he does (like laughing when he's funny, smiling, telling him it was nice if it was nice, etc, nothing more).
Don't fuss, relax, and date other guys at this point to stay focussed on your own value. no one should be expecting exclusivity yet. When he returns, he'll contact you if he's still interested. And whenever he does, if he does, you wouldn't have been sitting around waiting for him like a desperate girl. Even if he won't know that as fact, your energy will wreak of desperation because you're new at this and think you have to invest your thoughts and feelings on a guy who still doesn't deserve any emotional investment from you.
You're a catch, you know that? But, as a feminine energy woman, you will not be a catch if /you're/ the one who's trying to prove herself to him. Let him do that, he'll be into it unless there's no spark between you, and no one is at fault for that. You want a great guy for you, not necessarily /that/ guy for you. So let him go, there's no loss in your situation. Stop obsessing over this stranger and get back to focussing on yourself, you're amazing!
I hope this helps you. If you want some free coaching sessions with me, I'd be happy to help you over PM. Just let me know :)
