So sorry for both ladies in these relationships with turmoil. If you are still living with someone, you are still in a relationship with them, especially if you are worried of what bills he will have to pay, where he is sleeping, his feelings etc. I hope one of you isn't already justifying your partner's actions when and if he eventually brings home a new partner to sleep with. Do you have children in these living arrangements? If there are daughters exposed to this, remember they are learning from what they see mommy do how to have their own relationships someday.
