I love him but I need to let go

I love him so much but it's to much to go through 

He acts like a child while having to raise on

So hence the burden is left on me 

I can't live like this for the rest of my life

I am tired of talking and tired of feeling utterly alone in this relationship 

I keep saying I'll go and yet i still stay 

What is wrong with me. I need to let go.
