SO is very IMMATURE 😡😡

My SO is very immature and I HATE IT. It's like he never knows when to be serious... 7 years ago when I was pregnant I was diagnosed with DIABETES....and after I gave birth my diabetes stayed...so you can imagine HOW much my life has changed...talking about it is touchy-feely subject for me...my SO says I never open up to him.... And just when I do the bastard makes a joke about the situation.....uuuggghhh 😤😤😡 the shit really gets to me cause if no one else should be here for me HE SHOULD....ooohhhhh and GOD FORBID I SAY this then I'm being a baby AND I SHOULD STOP FEELING SORRY FOT MYSELF...it's like I can't win ALL I WANT IS HIM TO SAY BABY ITS OK.... I'm here for you... I'll never turn my back on you..... That's all I want every now and then.... HE ACTS like he's to much of a MAN to have a sensitive moment 😡😡😡😡😔😔😒
