It is normal for lovers to quarrel, and it can even be regarded as a lubricant of feelings. I hope you can communicate more when encountering problems. If you want to apologize to him, I think you can choose these as apology gifts:
Cross-stitch is very popular nowadays. You can embroider a cross-stitch for him yourself, a pair of pillows or a couple painting; if you want to be more special, you can customize some personalized military cards, bracelets, necklaces and rings. Boys generally like girls who pay attention to details. You can choose some items he needs in his daily life to give him. Computer bags, wallets, belts, razors, etc. are all fine. If you are a good cook, cook a table of delicious meals for him. Isn't there a saying like this? To capture a man's heart, you must first capture his stomach.
In fact, no matter what gift you give, as long as you prepare it with your heart, I think he will be moved. After being moved, he will definitely reflect on his own shortcomings!
