1. if the son is already there four days of the week, there must be room for him.
2. it is her partner's son, and if she is thinking of having a future with this man, I don't think making a difference of MY children, HIS children is the right way to go about this.
3. if the mother does not want the child, how can you push him away without feeling absolutely awful about it?
4. if she needs help with the children, I am sure there is a way of getting it.
5. if she works full time, there must already be someone else to look after the child/children.
6. I would think a two bed house is not even suitable for a family with two children, so long term thinking, they must have considered moving anyway.
7. I can see her worrying about extra work, but I think if she and her partner discuss this calmly, there will be a way.
