Hi,
I lives with my boyfriend about 10 years now. We are not married, but we live like a marriage couple. I pay all household expense half. The only thing I did not pay is the down payment for the house which he brought it 10 years ago when we met. The relationship has gone bad. He has tried to cheat on me with other stranger. I just found out the details. He denies it but I have all the evidence.
What kind of right do I have if we split up? Do I lose everything? We live in New York.
Please help!
