1. Clearly understand the problems you are encountering.
Is the reduction in the time he spends with you a sign of infidelity, or does he simply want more personal space? Is his temper worsening due to work stress or is it just his true nature? Problems in a relationship aren't scary; what's scary is not wanting to find the cause. How can you solve it then?
2. Stop criticizing and complaining.
Constantly criticizing your partner will only provoke their resentment. Expressing anger will not only fail to improve your relationship, but will also backfire and cool things down.
3. Let's travel together.
Many couples experiencing relationship problems use travel to improve their relationship. A new city, a new environment—it's like an adventure, something you need to experience together. Those long-lost feelings of intimacy might just rekindle in the warmth of spending time together!
4. Learn a new skill
A mundane life is one of the biggest reasons why relationships break down. Learning a new skill (of course, it's even better if you do it together!) can help you create more topics of conversation. It could be a sport or a language, injecting freshness into your relationship.
5. Improve your communication methods
Many problems in relationships stem from poor communication. Learning new and effective communication skills may help improve these issues.
