How do you break up with someone you have been living with for 8 years?

I have been this guy for 8 years. He moved here to be with me. This is kinda hard because we have been together for so long. However he is 18 years older then me. He is 46 and he has no Job. He has been in and out of Jobs for the whole 8 years. He does not care to see me work 2 jobs just to make ends meat and then still not make that. He has been complaining about the food I cook and always makes this face when I serve him his food. I tell him we should be glad we have this and then he just looks at me. We have moved so many times and a couple of times we lived with friends of mine. I have seen evidence of where I could accuse him if cheating ,but never actually caught him in the act. I have put a lot of my life on hold including school for this person. The problem is I am tired of it. I can't take it anymore. I am tired of him yelling at me and being so cold to me. I am tired of jewelry missing and things being done behind my back. The problem is I do not know how to end it. We are comfortable together as odd as it seems. I know it sounds funny ,but I am afraid of what will happen to him. He has no friends ( he seems to always offend people.) He has no Job so he can't keep up the rent. I have a place to go and will be okay. Guys please I need help no smarty answers this is something that is really bothering me. I need help and sincere answers. Thank you in advance.How do you break up with someone you have been living with for 8 years?
The first step in ending things with this man is for you to think more of yourself than you are thinking of him and his circumstance. You need to look out for you. He's a man and he's leaning on you far too much and the worst part about that is he isn't even grateful. He's taking you for granted and from what you say there is a trust factor that's lacking. You can't even trust him. You need to look at your life and ask yourself if this is what you want for the rest of your days. You know that it's not. When and if things do end you will feel a lot better. He is a burden to you and you need to lift that burden off of your shoulders. You do deserve better and you know it. You can't put his needs before yours and live that way for the rest of your life. Make that move sooner rather than later and know that when you do, he is not your responsibility. Don't even feel bad about it. You must put yourself first. Trust. ';-() How do you break up with someone you have been living with for 8 years?
Tell him just what you said hear. He needs to grow up and stop letting you take care of him. You need to get a life all so. He doesn't seem to mind that you are doing all of the work , he sounds more like an elderly parent who can no longer take care of them-self. It is time for you to just tell him and let go. You are suffering in this relationship, You have put your life on hold, waiting for him to get some ba**s and take charge. Well it is now time for you to do just that.Good Luck, And 18 years is far too much of an age difference, It would be different if he were contributing to your relationship and your life together.
