Most Helpful Girl
Along with being Sporadic, which he is here, dear, and along with his "Having family problems right " as well, he is wet behind the ears in years, I call it, and may be enjoying a bit of freedom and fun with his friends and may not be raring to be, from time to time... Hooked at the hip in a Real Relationship.
He has the sure signs of what I can see here, of Not wanting to always have to answer to you, which infuriates you and can put a monkey wrench in things in any relationship when you feel as though you are being put on a Pay no mind list. And from the way he was crying, wanting to end things, yet 'Earlier in the day he was like talking about having kids and stuff,' this may be some of his long term goals that one day he would Like to accomplish but for now... he is confused.
Give him his space and see what happens. You both need to get on the same page and either compromise or just... throw in the towel and stay friends.
Good luck. xx0
