While it is possible for a narcissist to value someone, it's essential to understand that their version of "value" is often based on how that person serves their needs and feeds their ego. Narcissists are primarily focused on themselves and their own desires, so any connection they have with others tends to be instrumental and self-serving.
Regarding missing someone, a narcissist might claim to miss you, but it is more likely that they miss the emotional supply you provide for them rather than a genuine emotional connection. Narcissists can become emotionally attached to people who provide them with validation, attention, and support, but it's important to recognize that their attachment is rooted in their need for narcissistic supply rather than authentic love or empathy.
If you find yourself becoming an emotional outlet or safe space for a narcissist, it can be a challenging and draining situation. While it may feel like they are confiding in you and that they trust you, it's crucial to understand that this dynamic is often one-sided. Narcissists are skilled at using others to offload their emotional burdens and seek validation without reciprocating the same level of care and support.
As you mentioned that the magnitude of his issues is becoming overwhelming, it's important to prioritize your well-being. Being closely involved with a narcissist can be emotionally taxing and may negatively impact your mental health. Running may indeed be a viable option for your own self-preservation.
Remember, it's not your responsibility to fix or carry the weight of someone else's emotional baggage, especially if they are not willing to address their issues or work on improving themselves. Consider setting boundaries and seeking support from friends, family, or a therapist who can help you navigate this challenging situation. Taking care of your own mental and emotional health should be a priority in any relationship.
