Wow, you have hit that nail right on the head RCR. My MLCer has always tried to make me feel like I should be grateful and appreciative for what he is doing for the house and the time he spends here and the bills he pays etc...all the while living with and having relationship with OW.
I think you were probably meaning that last paragraph for me instead of CrazyJourney, or are we both dealing with same issues after 4 years? (I'll have to go back and read her thread).
I will answer why I have "put up with allowing him access to the house"....
My MLCer is VERY controlling. When I have asked him to knock in the past, he agrees to it and then within days is back to letting himself in with a key. Or he will knock and then 2 seconds later..enter. I suppose for the most part, I have dealt with it because he exhausts me. He is worse than a 3 year old that doesn't listen.
Then on the other hand, I think I wanted to attract him back to the home in a way. I had read a lot about making yourself and the home attractive by good smells (ie; cookies baking, food cooking, his favorite perfume, clean home smells) and also making other aspects of the home desirable and essentially making it "home." So in order to do that, I had to let him come over, hang out...get a good idea of what he could be missing if he was not allowed in the home. At some point, I had planned on setting a boundary to where he was now allowed access to the home anymore, after he had a good long taste of what home was about. I guess I just hadn't gotten mad enough at him to fully put the boundary in place. Well that, and "you get more bee's with honey" kept going through my mind because in my situation it is VERY true. The more I was easy to deal with and let him go through that revolving door, the easier my life has been in dealing with him and the financial situation. Once I put up boundaries, he likes to take things away from me or make my life harder (a good example is when he shut our checking account down without telling me. Little did I know that banks only require one person to close an account).
So before I make this a huge long read, lol...I am ready to start setting those boundaries. I know I will get monstered at. I'm not so sure I'm ready to deal with Monster...but there really is no other choice at this point. I either tell him that he has to stay out of the house or I will end up having to move out.
