Dating as daca

I don’t know even know if I want advice or anything of that nature but I just want to vent a bit lol

I’ve been dating my bf for almost five years now and we have had talks of getting married before but he’s never actually gotten to proposing yet and I’m stumped on why

My dilemma here is that I am obviously in limbo and he is aware that getting married would benefit me a lot more than it would benefit him. I am starting to get to my wits end and have been debating ending things. In my eyes it’s hard to understand that someone is aware of my situation and would not jump to the idea of helping me in whatever way they could, like I would for them if they needed it. He did co-sign on a house with me that I would not be able to continue paying alone if I were to lose my job due to daca ending, so that’s something that’s also confusing to me, if you already agreed to buying a house why not get married too??

I understand it being wrong to just wanting to get married for papers, which I don’t think that’s all this is. I do love him dearly and it pains me whenever I think about us breaking up, but right now we might be in different paths of life and it would be extremely difficult being together while I’m constantly worried about possibly not being in this country for much longer. I understand it’s not fair to ask this much from him too.

And maybe he’s not the one?? we don’t argue much at all but I do get frustrated with many things he does at times. It really sucks thinking about having to start over again with anyone else knowing that this is the most vulnerable I’ve ever been with anyone and to have to throw it away, or even if he does agree and we do get married, it would feel almost as if I was forcing him to do something that did not come from him.

Idk I’m also getting older and seeing everyone else around me get married and living their lives is starting to get to me?
