My boyfriend who has been in love for many years sent me a short message.

It depends on why you broke up with him. If it's because of some trivial things, disputes, or young people don't understand love, or because one of you is not firm, then you can give him a chance (if you don't have a boyfriend now), because he has remembered you for a long time, and he must still like you in his heart, otherwise it will be difficult to persist for two years without interruption. Based on this, you should give him a chance and yourself a chance. If it's because of his personality or personality problems, it's hard to change. Even if I like you, it may not satisfy you. You can test him. If it does change, give it a chance. If it doesn't change, it will be resolutely broken.
