Missbopeep -- So just a short one from me. I believe to the contrary- that sometimes the words people use are not accurate. I know people in RL who post on various forums on MN and they've confided how they become really annoyed ( off forum) because posters misread , misinterpret, and misunderstand their posts, and then they have to keep going back, saying 'I didn't mean that, I meant this.'
So in other words, you believe in reading between the lines? All anyone knows of anyone on MN is the precise words they use. Words are never random, and those people who say 'I didn't mean that, I meant this...' are often people who are deluding themselves over something, and of course it's not obvious to them but it is the thing that hits readers right between the eyes. If more than one person misreads, misinterprets or misunderstands someone's OP then I think the poster should put on her thinking cap.
Gehj -- I begged my late Mother to leave my Father due to his Emotional and Physical abuse but she didn't have the strength to do so. As a result of my upbringing, I vowed no man would ever treat me that way. But.... I did allow my husband to be Emotionally abusive towards me during the four short years we were married because I actually didn't recognise it at the time!
You have been abused by your BF for ten years too. He used you. It seems you have been conditioned well by your family of origin.
If you teach English then you would know that you didn't use a metaphor in your OP. Even if you don't teach English you would know that.
the excuses and lies we were a part of -
You should use the active voice when referring to excuses and lies. You weren't 'a part of' excuses and lies that were floating around in the air. What lies did you personally tell and what truth did you personally not tell? (and same for excuses). A relationship that involves lying and excusing really is a shambolic one. You need to accept your role in the lying and the excuse-making. It will hurt when you realise how much of a ride you were taken on and it will hurt when you start to explore why you allowed this, and you may not like the person you see in the mirror when you start working on this, but you need to do this and resolve never to be that person again.
You're not a leaf blowing in the wind here, helpless when faced with the question 'what is the right thing to do?' (not 'what is right for me here, and now?'). There is nothing in your upbringing or in your marriage that entitled you to do what you have done.
What your BF wants wrt leaving/moving is not relevant here. For your own emotional health you have to stop this relationship and go cold turkey. However you arrange this you really have to do it without regard for the wishes of profoundly selfish other people.
