I'm a recovering alcoholic who kicked out her alcoholic ex. We share a child. This is the second time I've kicked him out. I feel I am changing, but honestly I don't think he ever will. He does not want recovery, and it doesn't sound like your boyfriend does either.
My ex's stuff is still all here. He absolutely filled my house with his junk. I want to sell my house. I am left with a big mess. He has been very hard to get rid of, as you can see.
Please get rid of this man now before it gets worse. And it will.
Best wishes to you. A lot of us have been in similar situations and are trying to help others from going down the paths we did. Hugs.
