It's a very sticky situation being that you live together, but he's made it pretty obvious that he doesn't think there's anything to discuss. I say evaluate what you want and take the steps to get it. (Warning: the preceding statement in no way indicates that you'll get what you want FROM THIS GUY, but unless you take actions toward your goals, this type of situation is liable to turn up again.)
Good luck with whatever you decide to do.
He's getting what he wants, so why would he change?
If you are getting what you want, then don't change either. However, if this is not what you want, then I suggest stopping what you are doing and direct your energy elsewhere.
Pretty straight forward solution.
1. Be careful how you tell him, if you decide to tell him. You live with him and this could get ugly...even though he isn't showing any emotional contact. Since he IS getting what he wants, cutting that off suddenly is going to become an emotional shock.
2. We can go into more details in how to set him straight if you like, my point above is just to be careful about how you do it. He is getting a sweet deal and he won't want you to blow that on him...even though I agree with previous posts that if you arent satisfied with this that you should end it.
3. Have you tried to talk privately or in the house only? Sometimes its easier to talk on neutral ground, but he's clearly wanting to maintain privacy at least. He might be interested in more but finds the situation rather awkward. Suddenly finding yourself living with someone you just met and had intimate contact with can be quite a shock to the system. He might just need some talking to, but my instincts tell me he needs to grow up a bit...he shouldn't ignore you after you two have shared something so special as this.
4. So in sum, I concurr with previous, he has what he wants, he isnt' going to change that and he is going to RESIST any attempts YOU make to change it for him. Gradually ease him out of the loop and into the reality of adulthood and maturity if you aren't satisfied with this...if you try to pursue more with him, its likely going to be a constant battle with him resisting commitment and openess from start to finish. Find someone who WANTS to talk to you in the first place..this fellow clearly doesn't.
Being a single woman after being in a relationship is hard. I'm sure I'll get flak from the guys because I'm definitely stereotyping here. I dont want to open up the "it's hard to find someone to be intimate with" can of worms (believe me, it's not pretty in there), but I've been known to do some pretty crazy things if I've had no intimacy in my life for a while.
Dust yourself off. File this one away under the "well, I tried it and that didn't work" category, and move along. Until they start tattooing the numbers on our foreheads I think we're ok. And even if they did, we'd still be ok. We are our harshest critic (most of the time).
You didn't agree mutually by open and honest communication to flirt, be nicer, be more prompt, be more patient with one another. You promised each other to have the horizontal mambo...and you've done it and are continuing on with it.
It's sex...it's just a physically pleasurable and gratifying act between two consenting adults - and it's only pleasurable and gratifying if both of htem are skilled at the sport. That's it.
If you want flirtation, cuddling on the couch, and someone to respect your words...you need to get "a boyfriend" that respects and admires you as an individual and considers sex with you an emotionally bonding experience as a result of that respect and admiration - not a bone buddy.
I would imagine that this feeling you are having is affecting the sex. How could you not wonder if tomorrow is going to be the same? If I were you, I would have a brief discussion that goes somewhere along the lines of, "Your failure to even acknowledge me during the day is causing more pain than the sex is giving pleasure. I need to feel like I am something more than just a warm body to you, and until I feel like I'm someone special to you, we cannot continue having sex."
Saying this is the easy part. Living it is the hard part. If you say it and don't stand by it, you will lose respect in his eyes and he'll know he can give you as little as he wishes and still take what he wants.
