Am I missing something? Advice?

He could be really genuine with his actions. I wont say that all guys are dogs, cause they aren't. There are some really nice guys out there who still know how to treat a lady. (sounds like the kinda guy you have) But, It's only been 3 weeks. It's not enough time to really be able to tell if that's the REAL him or if it's all just a front to get more than what you may be willing to give. Some guys can really play the game well. You'll be able to tell a little later on down the road what his intentions really are. Something will come up to where he'll be tested. If later on he gets mad over little things or because you choose not to have with him when he's expecting it or something, then you'll know that's really what it was all about. So, I say just give it a little more time and his true colors will be more revealing to you.
