I live with dp in his house- he kept saying he would put me on the tenancy but it hasn't happened yet. I just pay for it lol.
OMG.
Leaving the DSS issue to one side for a moment, this is totally shit and unacceptable.
You live in his house, that you have NO title to? Yet you pay for everything and do all the legwork when it comes to HIS son?
I know you say he's a good man, but a good man would not let the woman he purports to love be in that position.
What do you get out of this at all? You're chucking money away on a tenancy that your name's not even on. He could kick you out tomorrow and you would have no recourse. And all that money would be gone.
I'm sure it doesn't feel like this when you're living it, but it reads like he really saw you coming.
Please stop wasting your energy helping someone who can't even give you the most basic security of having a roof over your head.
Get out now, before you waste even more time, money, emotional energy and childbearing years on this user.
Sorry if that sounds harsh, but you are obviously an amazing, compassionate and supportive person and you deserve way better treatment from him.
