First, show your girlfriend the current situation. Money is tight, she really can't afford a house, so even if her girlfriend insists, it won't have any effect. But this doesn't mean that she won't buy a house, just that time should be delayed, her attitude should be clear, and she should communicate well with her girlfriend. If her girlfriend is still pestering and even threatening to break up, then I don't think this relationship needs to be maintained, because this girl doesn't know how to respect the other half.
Secondly, I hope my girlfriend can understand you. Sometimes it's not that we don't buy a house, but that we are in a difficult situation now. Never choose to break up with your girlfriend directly because of some trivial things. After all, his appeal is to have a perfect home, and the house is the foundation of a home. We have to admit the importance of the house. A relationship needs economic foundation as support. You should consider your girlfriend's feelings and hope to get her understanding and support.
Of course, another way is to borrow money from your friends and relatives. After all, nothing is difficult in the world. If you really want to buy a house, you can borrow money from people around you. The house price is really high now. Many young people are eager to get old or borrow money from people around them for this down payment. If neither of them has a house of their own after marriage, will the woman feel helpless? Thereby causing greater entanglement.
