It sounds like you have no legal rights to the house hes just basically having your share to personally be able to pay the house yet no legal bond but only his. If you are both moving in and want the house for a future doesnt mean that it means putting a date to your relationship. Thats an excuse. Its a safety stop point see if your able to continue paying and then you give another date. Mortgages take yrs to pay with 2 work pay unless you can afford more to make payment quicker

And aswel i hope and wish not but if all fails in the furure all your money you have put in you will gain nothink back. He will legally have full rights to keep house. Your basically just helping him afford it and live in it. If its a two way thing would he have your name on the mortgage and he do what you do? Just pay. What gives him the right to suggest he has that. Its both your desicions and 2 action(money) but one legal owner. Is it says ther. The legal owner. Instead of the house. Protect how you go about money. Your name should be on that. He may of given them your salary and his to get thru to the next stage of The legal actions They wont question him on why only he is signing i dont know. But why wasn't you present when he whent thru all paper work.
