Goodness where do I start!

I have been a long time lurker of the forums and to be honest pretty much read nearly every post in the adult step forum and here is my story. 

Married my wife at the tender age of 23 while she is 9 years older than me with two sons at the time were 11 & 15. The 11 year old lived with us but the 15 year old was in a home due to his behavior and his mother been unable to cope with him. Wife had the 15 year old when she was 17 and never really had any support with the rasing of the children. BF no where to be seen in and out of prison most of his life so no issue there. Both sons have had huge issues over the years from prison, drug addiction, theft amongst many other things. Early on in our relationship my BS was born when I was around 25 so we decided to get married on the back of that.

I have never felt any love or care to any of the the SS for as long as I can remember, they have robbed me, broken into my home, Ive had to pay drug dealers off, they have threatened me with violence on more than one occasion. Ive have always hidden my feelings the best I could toward them over the years. She has however thrown them out before when things got really bad but they end up on the streets hooked on drugs so you can imagine how she feels about that. I have criedd so many times over the years and said to myself that once my own BS was old enough it was time to go and here we are!!!

So 3 years ago oldest SS after another stint in prison was due to be released and both me and the wife decided to give it one more chance with him (her more than me) so we did. He is off the drugs and we managed to help him get a full time job. But now I have a 34 year old MAN CHILD living in my home. He pays very little rent, does not chores what so ever the wife even cleans his room I cook all his meals and give him lift repeatedly. If he asks for something and we say no he will stomp about like a spoilt child. I have wanted to leave in the past but could not leave my own BS with these idiots and kept my feelings to myself for many years somewhat

So last week we asked him to do a job for us and he had the cheek to try and charge us for the work LMAO and at that point enough was enough. I told my wife I want him gone and that they have made parts of my life a misery for years. She took his side of course (guilty mother) for the mistakes she made when she was young and she decided to leave as she will always choose her kids over me (grown adults). So here we are, Im am scared, positive, liberated and saddened. My BS is 16 now so we told him a couple of days ago. The adult SS who lives with us is unable to function without his mother and it drives me crazy!!

I think I am writing this today for comfort, to tell a story? im not really sure. I just know I need to be strong and follow this though as its never going to change. Maybe its my fault for not setting the rules, maybe its my fault for letting him back in the first place? 

To add to this the younger of the SS does not live with us but is a full blown drug addict with two of his own children whom we are banned from seeing as I didn't want him to have anything to do with my own BS but thats another story.

My parents have been very supportive over the years and know the issues I have had along with close friends. Nobody in the world would blame me for this and think the only mistake I made was letting it go on for this long. i know the ending to the story but now need to be brave enough to finish it.

PS apologies for any grammar I have a form of dyslexia
