Obviously, your boyfriend is selfish in life. It makes no sense to borrow money from that woman for her own use. It is no problem for a person to make a living through his own hard work. However, your boyfriend often borrows money from others, which proves that his daily expenses are very large, his income cannot cover his expenses, and he even has some gambling habits in his life. I think you should pay attention to it. When borrowing money from you, refuse it decisively and postpone saying that you still borrow money from others.
You can also tell my boyfriend that his parents have his money. You can also say that he still has to pay back the loan every month. He has no money in his hand and his daily expenses are very high. It is impossible for him to store anything in a month, so he must show his refusal in time. If you refuse politely, the other person may feel that he will keep pestering you to borrow money if he has the opportunity.
Couples are only in the stage of getting along, and they don't know each other well enough, so we shouldn't lend money to each other easily without knowing each other very well. If we know each other's personality and find that they are generous in spending money, and they don't know frugality, and even have some bad habits such as gambling and smoking, then we should be more cautious when borrowing money. Couples may break up at any time, but it is a very painful thing for women because of interests.
