A&K maybe you need some space from him so you can try to figure out what you want out of your life. Yes you want him home, but if he never comes home what do you want your life to look like? Torturing yourself with thoughts of all of the amazing people he's meeting and all of the amazing things he's doing isn't going to help at all. Besides, who's to say that it's really all that amazing and he's not just saying that because he knows it's the fastest and easiest way to make you feel bad about yourself. If you've been DB perfectly and he's noticed this could be his reaction to it.
It sucks and it's hard when the person we're in love with rejects our love and flaunts how "great" not having us in their life is. But I have to question how authentic they're being. At this point in your relationship he's going to be a selfish pr*ck. It's the nature of the beast. Do your best to not focus on it. Do your best to really GAL. Do your best to act as if his tales of the fast life don't mean a thing to you. Sooner or later it won't be an act.
