I (24m) am struggling on what to do with my girlfriend (24f) about her family.

So, i love my girlfriend, and i know for a fact that i do want to marry her eventually (once i establish myself). We both have very traditional families and im struggling because hers is very traditional AND overbearing. She currently lives with her dad and i usually come pick her up and she spends the weekends at my place. The issue comes up with her toxic mother and overbearing grandmother. They constantly message, call, and sometimes show up at her dads house unannounced looking for her for something. So she ends up having to come up with an excuse to get them off her case and its just gotten worse.

Its become so stressful and I’m so tired of having to deal with the constant stress of sneaking around. I feel like a teenager and its moronic that we have to do this. She cant get caught by her mom or grandma, because they’ll have a conniption and tell her dad to not let her see me anymore and her dad will just go along with it i guess.

I currently live in an apartment owned by some relatives but i cant have her move in unless were married (i cant afford to move out). So now it feels like i either have to live with this constant ball of stress (cause at any point i could be told we cant see each other anymore), break up, or propose tomorrow. Im just so tired, and im so anxious over the whole thing, i just want this to stop. I genuinely dont know what to do anymore, please someone give me some guidance here. Is there anything i can do here?
