What the ****? I understand what you're saying, and that it's not that you really wanted anything, you just would have liked some thought, but why would you bring up such a topic?
I probably would have got somebody something at 6 weeks in, and you probably know him well enough to decide if he's selfish or not, but if he has the money and didn't get you something it's probably because he doesn't want to take it much faster. I always feel this obligation to buy somebody something, even if you been out with them for like 2 weeks then Christmas pops up or something, but that's more out of fear for them getting me something. He shouldn't have to buy you anything at 6 weeks, I mean in that time you don't necessarily deserve gifts from him. You should earn them, and 6 weeks isn't enough. His gift for you being with him for 6 weeks, is him reciprocating.
EDIT: Oh, just read what you said about looking at houses. Nevermind, my post is void.
