Any man that tells you he wouldn't marry you because his parents wouldn't let him; that's either an excuse and distance-holder or you don't want that boy, he's not a mature man in charge of his own life.

Too, if he insists you text him while he's at work but he refuses to reply during the same time, he's not mature. I had a boyfriend like that once; I went across country to visit him and his family and we went to the California State Fair where he got all into playing video machines in a tent! He wouldn't stop, even started begging me for quarters and when I got bored and moved away, it happened that I had been blocking the sun and he got all bent out of shape, trying to make me move back to the spot to continue blocking the sun for him to play!

I would move on if I were you; he wants a play toy for himself.
