Hello again Poppysquad
You are doing amazingly well
and please don't be surprised that you feel so confused. Your DP senses that you are changing towards him and that you are seriously thinking about ending this relationship, so he is going into emotionally abusive overdrive. This is what men like him do. He is trying to undermine you even further so that you stay.
Over the course of your relationship your DP has planted so many negative thoughts about you and your ability to cope as a partner, woman, and mother, in your head, and repeated them so many times, that you have come to believe them. But they are not true. They are just what he says to you - no one else. Not your son. Not your friends. Not your colleagues and no-one here.
I've had this done to me and it is beyond horrible. Only on Friday my recently Ex-DP almost reduced me to a blubbering wreck after a chance meeting in a local car park. We spoke and, with a smile on his face, he subjected me to a five minute barrage of criticism about what a 'useless mother I am', how my 'doormat attitude has turned my children into money-grabbing monsters', what 'a slave I am to other people' and how people only bother with me because I 'do things for them' and not because they might like me or love me. Now I know this is all big fat hairy bollocks, but, as you can imagine for an hour or two after that 'conversation', I did feel like shit on a stick. And but for chat on the phone to wonderful my BF I would have been a blubbering wreck for sure. But she reminded me that Ex-DP knows exactly how to press all my buttons, because he would take something real, but minor, and then blow it up into crazy proportions, so as to make me question my own judgement. And that he was doing this to undermine me so that I would go galloping back to him as 'the only person who was really any good for me
. Needless to say, I have not done that. And thank God for my BF.
You see, men like my Ex-DP and your DP, they will target a weak spot and work on it and work on it and work on it until you just don't know what is right, and what is wrong, any more.
Your lovely son sounds like a totally normal 19 year old, and all teenagers can be anything and everything from utterly wonderful, to nightmarish, all in the same day. It's how they are. But your DP is a selfish, cold an unempathetic man, blaming you for your son's 'inadequacies' which a) are not inadequacies at all, just normal behaviour and b) even if there were problems beyond the normal there, your DP, if he was a half decent bloke, should be supporting you to deal with any such issues, not blaming you for them in the first place.
More reflection: I think one issue that has impacted on things is my lack of ability to deal with my son when there have been issues. I did ask my son not to let anyone sleep in my partners bed. But he allowed it. I did not jump up and down and shout at him or tell him that here would be consequences and follow through. My partner thinks I should. He thinks the fact that there hasn't been this discipline in my sons life has led him to be the person he is now.
Your DP kicking off about your son letting someone sleep in the spare bed is totally out of order. It's supposed to be your son's home, for goodness sake. Not a shrine to this man's ego. You do deal with your son's behaviour - just not in the over-the-top, dictatorial way that he thinks you should.
We are all with you - you can do this. Please end this relationship now. Your DP cares more about the railway sleepers on your drive than you. And please do not worry about decorating your house.
Is it in joint names? Do you have any idea how much you could get for it? And how much did you both put into it?
