My boyfriend is very upset recently, but he won't tell me anything. What should I do?

Long-distance relationships are hard. Communication and tolerance are the only ways to maintain love. Communication, through various methods to communicate feelings, each other's state of mind, if organically gathered together, it is best to be in one place, which is more conducive to your's feelings. If we can't get together for a while, it is more important to maintain a healthy and balanced mental state. The premise of maintaining feelings is that both people's mental states are healthy and perfect. If a person can't be healthy, confident and happy, then two people will not be too healthy and happy together. Therefore, you should not only pay attention to each other's phone calls and news, but also learn more new things in your spare time, broaden your horizons, improve your spiritual world, enrich your spiritual world and increase your wisdom. When you always have fresh strength, he will feel it and be infected by you, and your's emotional ties will be stronger and communication will be more effective. Having a calm, confident and happy heart, a wise heart that can keep growing and expanding, is the inner strength to maintain long-term charm. So you should have confidence in your future, start from yourself, and then understand his thoughts, keep in touch and care, and understand his true feelings. What he is saying now is that it's no use giving you trouble. As for him talking to other girls, he doesn't care. You don't have to worry about it. It's your people, and no one can take it away. Jealousy and resentment are useless. If you are not so greedy, you will give him more attraction, and he will naturally tend to you.
