Ok. Well you better have a talk with him.

And you know nevermind the fucking stooges, you're his girlfriend you come first. I mean he said himself he wants to marry you, you don't marry someone who is less than one of your friends. The one you marry is your best friend, IMO that holds true for the one you choose to fuck too as it's the same thing in my eyes, but hey I'm a minority so what does it matter?

I'll say as I fear, he just wanted to fuck you, everything he said and felt were vessels to get him there. Now that he got what he wanted he's just indifferent, the only reason he hasn't broken with you is the prospect of more fucking and not to shame himself for all the bullshit he pulled out of his hat. If anything he might try to wear you down with his indifference so you leave him instead, which would save him the embarassment. He can still do you in the meantime so he doesn't mind.

Maybe he didn't even plan for this, but he had his priorities wrong from the beginning, he got his passion for you from his crotch and not his heart. Evidently, because otherwise he should be even more loving towards you now when you have recently strenghtened your bond, fucking or no fucking.

......I sincerely hope I'm wrong. And in case I am, don't take my words for anything until it's confirmed, but be prepared it may be like this.
