@Kayla-xo,
it is my opinion that most men have a fear of commitment, especially in the early stages of a relationship. commitment is fine as long as their mates don't find out.
talking of mates, man will always want to have a beer and chat about cars and sport with his mates. man not want woman to be involved in these affairs, and to be fair, most woman probably don't want to be stuck in the pub listening to her man and his mates talking about cars and sport.
as the relationship progresses, and things settle down, man will come to accept more and more commitment, until one day you are married, and his days down the pub are over. man will always fight this though. he is fiercely independant.
stick to your guns for a bit, it's still early days. bully him a bit if you want, but not too much. big brave man easily scared.
if in a couple of months things haven't changed, then it's time for "that" chat.
good luck, i wish you both all the best, and apologies for my blatant generalising.
