Would someone please give me advices? Please!!

I’m living in UK for the past 2 years, i met someone almost a year ago, he is a very nice person and always treated me well. We are living together but i have never felt comfortable enough to call this place “Home”. We share all the bills and also his Mortgage, as he own the house. All the time he refers about the house, he always says His house! Never our place or our home! I have offered even to help financially to change his carpets, but all i heard was.. “it’s ny house”. I never asked or will never ask my name on the mortgage, I’m just asking to hear “our home”. I take care of the house, i do all the laundry, all the cooking.. And I still can’t call this place “home”. I always refer as “his house” or “where i live”.
Many times he has mentioned about getting married, but never goes further than that! I tried to talk with him.. and it seems to go nowhere!! He never spoke with his parents about it.. As he promised he would!
He said they are very conservative! Which I don’t believe, i have met them.. And they are lovely!! His sister is gay.. And living with her partner, they all accepted her very well! As he is 30’s, I wouldn’t think it would be a shock to talk about a marriage.
Am I overthinking too much in the end of all?
I really appreciate everyone’s help, I don’t have many froends over here.. I’m feeling suffocated!!
