So I feel like you see someone you like and who you think may make a great partner, if only he grew up, ditched his mothers rules, didn't stay out as often in his social circle, was comfortable being an adult and sleeping with you/in your home, didn't talk to other women, hid his phone use from you, was more open to physical touch and initated it more.

So I want to ask, if there are so many things that are not working for you, then do you think perhaps that there is more things that he would need to change than most?

The best successful relationships are about finding someone that fits with you without needing to change themselves in any way, or at least close enough that you can discuss things in an adult way and come to an agreement.

This person looks nothing like the person you want to be with at all and I feel (and this is my personal opinion) that you are feeling anxious about getting your own place and he has come along and your fears are grasping onto someone to help you get throught this period of life, he isn't going to do that and has proved already that he isn't.

His family dynamic is also all wrong for you as his mother rules the household with even his older brother bringing his partner over to the house, so no independence there either.

I am sorry but I would throw this one back into the sea and let him swim away and catch one closer to your goals and values.
