What should i do😠😠😠

So my boyfriend of 5 years doesnt feel like its important to let me know personal business... he makes alot of moves with out me.... for example our transmission went out on our car 3 days ago and i havent heard anything about what he plans on doing... unless i ask!! Wtf.... i think im gonna leave him i cant take it... hes tooo private for me..... and when i get mad about him not talking to me... im wrong!!! he knows my every move and i dont know anything he does! We're to the point in our relationship where we dont even talk things through.... after arguements....
