I'm having a hard time balancing trust and being realistic about people, especially while navigating deep-seated insecurity.

I haven't really had my heart-broken, but I think that's because every time I start to fall in love with someone I lose all trust and emotionally cut myself off - causing us both a tonne of heartache.

Thing is, I feel like I just cannot trust a woman in a relationship. Some women I've felt more inclined to trust, but it all turns to suspicion and jealousy once I get emotionally involved and become exclusive.

What is the reality? Some women CAN be trusted, others can't? My only insurance is to be level-headed and critical about the kinds of women I get into relationships with?
