What you described sounds like behavior that goes beyond normal and healthy trust in a relationship, and it may be indicative of issues related to insecurity and paranoia.
Constantly checking your partner's phone, going through their emails, and following them can indicate a lack of trust, which can be damaging to a relationship. While it's natural to feel insecure or anxious at times, extreme levels of suspicion and distrust can lead to significant relationship problems and may negatively impact both your emotional well-being and that of your partner.
If you find yourself engaging in these behaviors, it might be helpful to take a step back and reflect on your feelings and thoughts. Consider talking to a mental health professional who can help you explore these feelings in a safe and non-judgmental environment. They can assist you in understanding the underlying causes of your insecurity and provide tools and strategies to build healthier patterns of trust and communication within your relationship.
Healthy relationships are built on mutual respect, trust, and open communication. It's essential to address any concerns or fears you may have with your partner in a constructive and respectful manner. Openly discussing your feelings can foster a stronger bond and lead to better understanding and support from each other.
Remember, seeking help is not a sign of weakness; rather, it shows your commitment to improving yourself and your relationship. A mental health professional can help you work through your emotions and develop healthier ways of coping with your fears and insecurities.
