Relationships are about compromise. That you must do all the uprooting and giving up what you have and who you are you are in fact on the losing end. He apparently is unwilling to compromise and lose any of what he has means he is winning.

The dynamics of his current living situation point to this as well. It certainly indicates that he wants to control what is in his life - that everything must be by his terms alone. The fact he wouldn't compromise when you first threatened to walk away only supports this.

His current situation and family dynamics really bother me. WHile his child comes first you should be paid honour and respect. SUpporting his child should not mean living in the same household as his 'ex' wife. If he can't support two households now, how can he support you?

While this may make you angry my recommendation is that you walk away - for good.
