OP the honeymoon period should last longer than what 6 weeks? 
Fair play you've come back and responded to what we've all been saying, but you have an answer for everything negative being said.
If you've already messaged his more before over things then I'm actually a little surprised you havnt.
Give him the benefit of the doubt if that's what you really want to do, but don't be surprised if this happens often.
I'd be fucking miffed if my boyfriend who I didn't know that we'll wasn't responding to my messages but taking advantage of my Netflix account.
If he spends so much money buying and treating you to things he can bloody pay £5.99 a month for his own Netflix
You cannot be sure that this isn't something he tends to do.
I've had this happen to me but it wasn't a relationship although we were very close, he'd come back months and months later, I got fed up of one minute us spending every hour of the day in contact and then the next he'd " have a sore throat" and do the exact same your boyfriend is doing to you...
I had enough of it in the end, wished him the best and ditched him. And that was someone who in a sense I did love.
If someone cares that much about you you don't ignore for 2 days etc, and he's obviously not thought of it in that way otherwise he'd have replied apologising for not being in contact
Who knows? We could ALL be wrong and you be right, but I can only see this going one way ...
