Hiya Nell6,
From what you have written i feel that your man has got the best of both worlds and with no real commitment or pressures, you say he is not romantic, so you probably wont get any flowers sweetie, he is as he is, you cant change him but only change your attitude towards him. If this guy was really serious wouldnt you think that he would have introduced you to his family by now? Try not to become too convienient for him, pull away a bit and see if he comes after you… If he dosnt maybe its time to move on and alone. Dont you deserve better?
I wish you all the best x
